Influence of heat treatment on photoluminescence spectra in ZnS:Mn crystals with hexagonal structure
Journal Title: Journal of Physics and Electronics - Year 2018, Vol 26, Issue 1
Abstract
It has been investigated the influence of heat treatment with the following temperins on the integral photoluminescence spectra and on the individual bands of this spectra. It has been showed the correlation between the changes of intensity of photoluminescence individual bands and real structure of crystal, controlled with the help of EPR method. The basic changes of photoluminescence and structural properties have threshold nature. They begin to show up at temperature of annealing T > 650o С. The maximum intensity of integral photoluminescence spectrum was observed in the region of phase transition crystal structure of zinc sulphide.
