The structural, compositional, and optical properties of as-deposited Cdo.sZno.2S films were investigated using X-ray diffraction （XRD）, X-ray fluorescence （XRF）, X-ray photoelectron spectroscopy （XPS）, and optical transmittance spectrum.

The composition of Cdl-xZnx S thin films monitored by a quartz crystal oscillator agrees well with that obtained from XRF and XPS measurements. The optical constants, such as refractive index, single-oscillator energy, dispersion energy, absorption coefficients, and the optical band gap, were deduced by the Swanepoel＇s method, in combination with the Wemple and DiDomenico single-oscillator model, from the transmission spectrum of Cd0.8Zn0.2S thin films.展开更多
