Photophysics of carbon nanotubes
This thesis reviews the recent advances made in optical studies of single-wall carbon nanotubes. Studying the electronic and vibrational properties of carbon nanotubes, we find that carbon nanotubes less than 1 nm in diameter exhibit dramatic changes in their electron and phonon dispersion …

The photophysics properties of lanthanide luminescent probes
A detailed study of the luminescence quantum yield, lifetimes and the number of water molecules coordinated to lanthanide luminescent probes based on biphenylyl-7-amino-4- methyl-2(1H)-quinolinon (Bi-cs124) derivatives have been carried out using a time- resolved fluorescence assay (TRFA). Bi-cs124 …

The Fundamental Photophysics of Fluorescent Carbon Nanodots
Carbon Nanodots (CDs) are a new protagonist of carbon-based nanoscience by which the paradigm of carbon as a black material unable to emit light has been completely revolutionised. They have been emerging as a new frontier in Nanoscience at the beginning of 2000s, and their potential is evident …

Photophysics of hexanuclear [Re₆Q₈]²⁺ cluster compounds
Introduction: The ability to determine and characterize the nature of air and fluid flows has become an integral part of numerous industries. In the specific area of airflows, the development of pressure sensitive probes (PSP), molecules sensitive to the pressure of air at a surface, has drawn much …

Photophysics of cadmium selenide quantum dot solids
Semiconductor quantum dots or nanocrystals have size dependent optical and electronic properties that arise from quantum confinement. While the quantum size effect is reasonably well understood, the effect of abrupt interface between the nanocrystal and its dielectric environment is not. In this …
