Abstract
Colored-oxide glass filters containing CdS quantum dots were found to exhibit third-order optical nonlinearity in 1983. However, the dot sizes were somewhat large and the size distributions were wide. The sol-gel method proved to be a better alternative for CdS quantum dot materials. This paper describes the advantages of the sol-gel method, and how it has been exploited to prepare two types of CdS quantum dot materials. These are fully dense sodium borosilicate glasses and organically-modified silicates, Ormosils. Both materials give high values of third-order nonlinearity and excellent optical transparency.
