摘要：

The mechanisms of photoluminescence excitation of Mn2+ ions in ZnS crystals have been investigated on the basis of complex analysis of the temperature dependences of the photoluminescence and photoluminescence- excitation spectra of ZnS:Mn crystals. The activation energy of a manganese luminescence center was estimated at Ea = 0.17 ± 0.05 eV. It is shown that Ea represents an energy band with a width ΔE a = 0.1 eV, within which a manganese luminescence center can experience radiationless recombination. ©2005 Springer Science+Business Media, Inc.
