Linear optical properties of Ge nanocrystals in silica

Dowd, Annette; Elliman, Robert G.; Luther-Davies, Barry


The absorption and extinctionspectra of Genanocrystals in silica formed by ion implantation are studied using photothermal deflection and transmission spectroscopies. It is found that scattering makes a significant contribution to the extinction spectrum, damping the spectral features and resulting in a Rayleigh scattering-likeω⁴ dependence. In contrast, the spectra measured by photothermal deflection clearly show features such as the E1/E1+Δ1 transitions. The Tauc gap is extracted to be...[Show more]
