摘要：
A comparison, of some structural and optical properties for pulsed laser ablated (PLA) and thermally evaporated (TE) CdSe thin films, is given. The stoichiometry of the prepared films is checked by energy dispersive X-ray spectroscopy (EDX). Electron microscope data indicate the polycrystalline nature of the films with hexagonal structure. The degree of crystallinity is improved in PLA films. Some optical parameters for the two groups of CdSe films were compared over a wide range of wavelength (similar to 200-2500 nm) at room temperature. The analysis of the data indicates that the dispersion parameters are affected by the technique of preparation more than the absorption parameters.
