详细
The temperature dependence of the spectral composition and intensity of intracenter luminescence of the Mn2+ 3d shell and the temperature dependence of the luminescence excitation spectra in an epitaxial layer of Cd0.2Mn0.8Te at different levels of optical excitation are investigated. It is found that in the crystals of type II1–xMnxVI with a high concentration of manganese, the characteristics of intracenter luminescence of Mn2+ depend on the efficiency of excitation migration over manganese ions. Under migration conditions, the luminescence quantum yield is determined by the cooperative effect (up-conversion).
