中文摘要	the raman scattering and the photoluminescence (pl) of znsxte1-x mixed crystals grown by mbe, covering the entire composition range (0 less than or equal to x<1), were investigated. the results of raman studies show that the phonons in znsxte1-x mixed crystals display two-mode behavior. in addition, photoluminescence spectra obtained in backscattering and edge-emission geometries, reflection spectra and the temperature dependence of the photoluminescence of znsxte1-x from 10 to 300k were employed to find out the origins of pl emissions in znsxte1-x with different x values, the results indicate that the emission bands, for the samples with small x values, can be related to the band gap transitions or a shallow level emission center, while for the samples with large x values, they are designated to strong radiative recombinations of te isoelectronic centers.
