【Abstract】 Infrared photo -acoustic spectra (IR-PAS) of the nanosized silicon synthesized by laser-induced chemical vapor deposition were studied by use of photo-acoustic spectroscopy. The influence of annealing treatment and compression on the IR-PAS absorption peaks of the nanosized silicon is investigated. The IR absorption peaks are assigned and the interpretation is presented. The influence of solid state effect on the absorption peak is discussed.更多还原
