Book Description :

The fundamental electronic states and optical properties of single-walled carbon nanotubes are briefly explained in this chapter. Moreover, the novel optical properties of carbon nanotubes revealed by advanced laser spectroscopy (single-nanotube spectroscopy and time-resolved spectroscopy) are introduced. Due to the enhanced Coulomb interaction, the optically generated electron-hole pair forms a strongly bound ‘exciton’ state, analogous to the hydrogen-like state in the carbon nanotubes. The striking features of excitons in the carbon nanotube, such as singlet-dark states and triplet states, which dominate the optical properties, are described in this chapter.

Book Description :

Fiber laser technology is attracting a great deal of attention due to its numerous applications in fields as diverse as micromachining, biology and medical sciences or telecommunications and its potential as a substitute for solid-state lasers in industrial and technological applications. Fiber lasers are also exciting from the scientific point of view as they are an excellent platform to further study and understand nonlinear optical phenomena. In this chapter, we review the impact of nano-materials, such as graphene and carbon nanotubes, in advancing fiber laser technology. Both graphene and carbon nanotubes present a highly nonlinear optical response, with a high third order susceptibility and saturable absorption. Here, we discuss how these properties can be used to achieve pulse operation using a technique known as mode-locking and how these two materials compare to other mode-locking mechanisms in terms of their ability to achieve pulse operation, the stability of the mode-locked lasers and their long-term reliability.

Book Description :

Because of their estimated ultra-high third-order nonlinearity, single-walled carbon nanotubes (CNTs) can be regarded as a potential new material for optical nonlinearity. The nonlinearity of CNTs is believed to originate from the inter-band transitions of the π-electrons, causing nonlinear polarization. In this respect, CNTs are similar to other organic optical materials that exhibit extremely high nonlinearity. CNT-based photonics devices offer several key advantages, including ultrafast response, robustness, tunability of wavelength, and compatibility to fibers. This chapter will describe the design and fabrication of CNT-based nonlinear photonic devices. CNTs with suitable diameters – and thus suitable operational wavelengths – are deposited or grown directly on different types of fibers or waveguides to ensure effective CNT–light interaction. Optical nonlinear effects including four-wave mixing (FWM), cross-phase modulation (XPM), and self-phase modulation (SPM) have been observed experimentally using fabricated CNT-based devices. Corresponding wavelength conversion and optical signal regeneration applications based on various nonlinear effects are discussed.

Book Description :

This book focuses on carbon nanotubes and graphene as representatives of nano-carbon materials, and describes the growth of new technology and applications of new devices. As new devices and as new materials, nano-carbon materials are expected to be world pioneers that could not have been realized with conventional semiconductor materials, and as those that extend the limits of conventional semiconductor performance. This book introduces the latest achievements of nano-carbon devices, processes, and technology growth. It is anticipated that these studies will also be pioneers in the development of future research of nano-carbon devices and materials. This book consists of 18 chapters. Chapters 1 to 8 describe new device applications and new growth methods of graphene, and Chapters 9 to 18, those of carbon nanotubes. It is expected that by increasing the advantages and overcoming the weak points of nanocarbon materials, a new world that cannot be achieved with conventional materials will be greatly expanded. We strongly hope this book contributes to its development.

Book Description :

Carbon nanotubes are exceptionally photostable fluorophores that emit in the near infrared range. Their novel optical properties make them particularly appealing for applications in biosensing. This chapter focuses on the state-of-the-art development of optical biosensors based on single-walled carbon nanotubes (SWCNTs); also, it draws attention to the basic photophysics of SWCNTs, optical-sensing mechanisms, and surface functionalization principles. The concerted efforts from the research community in the past decade have enabled the realization of several SWCNT-based optical biosensors that provide real-time, non-invasive analyte detection. We review the performance of these biosensors with regard to their sensitivity, selectivity and response time, and highlight the prospects and challenges of constructing biosensors for more advanced sensing applications.

Book Description :

The investigation into the behavior of the fluids in nanoscale channels, such as carbon nanotubes leads us to a new approach in the field of nanoscience. This is referred to as nano-fluidics, which can be used in nano-scale filtering and as nano-pipes for conveying fluids. The behavior of fluids in nano-fluidic devices is very different from the corresponding behavior in microscopic and macroscopic channels. In this study, we investigate the fluid flow through carbon nanotubes and graphene based nanostructures using a molecular dynamics (MD) method at a constant temperature.Three different models were created which contain single-walled carbon nanotube, graphene, and a combination of both. Liquid argon is used as fluid in the system. In the previous investigations, they were considered bombarding the atoms towards the carbon nanotubes like bullets from a gun, and due to the interactions, they lost most of their momentum. Thus, the chance for the atoms to pass through the carbon nanotube was very low. Here, we employed a new approach using a moving graphene wall to push the argon fluid towards the confinements of the systems. By performing this method, we have tried to make a continuum flow to find out how the physical quantities such as, position, velocity, pressure, and energy change when the fluid flow reaches the confinements of the systems.

Book Description :

The study of photophysical, electronic, and compositional properties of single-walled carbon nanotubes (SWCNTs), bulk nanotube samples, and graphene oxide is described. We show effects of external electric fields, causing dramatic, reversible decreases in SWCNT emission intensity. Quenching efficiency was related to exciton binding energy suggesting field-induced exciton dissociation. Further, we describe a new method developed to measure the fraction of semiconducting SWCNTs in nanotube samples. The results provide important information about sample electronic compositions that can also guide SWCNT growth methods. Next is the study of SWCNT absorption backgrounds. A number of extrinsic perturbations such as ultrasonication, functionalization, carbon impurities, and SWCNT aggregation were applied and their contributions quantified together with background component from metallic SWCNTs. These results can be used to minimize and evaluate SWCNT absorption backgrounds. Finally, a strong pH dependence of graphene oxide photoluminescence was observed. Sharp and structured excitation/emission features were obtained in basic conditions and assigned to quasi-molecular fluorophores.
