dc.description.abstract The absorption and extinction spectra of Ge nanocrystals 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-like ω4 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 ∼0.7 ± 0.1 eV. © 2001 American Institute of Physics. [DOI: 10.1063/1.1409591].
