Abstract

The CdS particles are irradiated by the green light from an Ar laser. The irradiation produces the electron-hole pairs and other excited states in the particle. The lifetime of the excited state is ca. 10 μs, which is extremely long compared with the recombination time of the electron and hole pairs. This long-life state forms an optical absorption band in the excitation-modulated transmission spectra. The relationship between the spectral intensity and the strength of the excitation light suggests that this absorption band is caused by the photoionization of the intervalence states and the change in the electrostatic field in the CdS particles.
