Optical applications of sol-gel nano-composites

Abstract

There has been a lot of research in the area of nanocomposite materialfor optical application. The optical qualities can benefit more technologically important forms, such as films and fibers. This paper covers the authors' results in terms of sol-gel nanocompositefor optical application over the preceding ten years. The sol-gel technique, in combinationswith colloidal technologies, can be used to make nanocompositesmultifunctional material focused on the integration of QDs in inorganic or hybrid organic-inorganic matrices, which have good optical property, chemicals stability, and are easy to process. Surface plasmon resonance (SPR)-based optical gas sensor show significant promise for better understanding chemical interaction at the nanoscales as well as the creation of actual device. Gas sensors with customised microstructure can be made by carefully controlling the film structure. The broad characteristics of the synthesis and characterisations of the material, as well as an findings obtained in specific situations, are detailed in both types of applications with the goal of providing an overview of the evolution of these materials.
