Abstract
Scandium has been known as coactivator of the luminescence of the ZnS crystals but is role in the photoluminescence and the thermoluminescence processes has not been well understood. The authors have used the EPR of chromium, which can act as both an electron and hole trap, and also ODMR, to investigate these processes. In particular, the measurements of the change of the chromium Cr+ EPR signal intensity in thermal or light-induced processes enable them to determine the energy depths of the important centres in ZnS:Cr,Sc. The ODMR experiments correlated the luminescence transitions with specific defects such as Sc2+ donors and (VZn-Sc) A-centres.Keywords
