摘要：

The band-gap energies of CdS grown by chemical-bath deposition are obtained by optical transmission and photoacoustic spectroscopy. These values and photoluminescence spectra are correlated over a range of thermal annealing temperature, in which the evolution of sample structure is characterized by X-ray diffraction patterns. With increasing annealing temperature, the band gap reaches a minimum value. If is suggested that at this temperature a transition from a cubic to a hexagonal lattice occurs.
