Luminescence of ZnSe(Te) crystals melt-grown from the charge and enriched in selenium

The evolution of the radioluminescence (RL) spectra and spectral-kinetic characteristics of ZnSe 100-x Te x (0.01 Zn - + D + }, where V is the Zn vacancy, a D-donor. The green-blue luminescence at 0.20 100-x Te x samples, corresponding to the whole range of x, is considered as an indication of the fact that the luminescence center {V Zn - + Te 0 + Zn + } comprises the isovalent dopant Te and the excess Zn.
