Qısa məlumat

In the given paper, the temperature dependences (T = 85-300 K) of the green band intensity at wavelengths λ = 529.5 nm and λ = 547.5 nm have been measured and observed, respectively, from the polished and unpolished surface (PS and unPS) of a polycrystalline CVD (chemical vapor deposition) ZnSe sample upon excitation by X-ray quanta (hvex ≫ Eg). In both cases, the activation energy of thermal quenching has been determined, and the reasons for thermal quenching have been considered in detail. Along with XRL spectra analysis, the temperature behavior of the green band observed upon excitation by an ultraviolet (UV) laser (He-Cd, λex = 325 nm) from the PS and unPS in the temperature range T = 80-200 K has been discussed in more detail.
