摘要：
The aim of this work is to investigate the influence of Rh6G concentration on optical and thermal properties of nanocomposite porous silicon-Rh6G. Photothermal spectroscopy is carried out in order to determine optical spectra and gap energy of nanocomposite samples which is found to increase with Rh6G concentrations. Photothermal deflection is used to measure nanocomposite thermal conductivity. Nanocomposite thermal conduction is enhanced by the insertion of Rhodamine molecules in the porous matrix. Also, Photoluminescence spectra show an enhancement of energy transfer from porous silicon to nanocomposite band due to Rh6G.
