Paper Abstract

Attempts were made to synthesize copper activated zinc sulphide phosphors sensitive to (beta) -radiation. In this purpose, homogeneous synthesis mixtures were prepared from luminescent grade zinc sulphide - thiosulfate route -, copper nitrate and alkaline and/or alkaline-earth chloride and were fired at 800-900 degrees C, in nitrogen atmosphere. ZnS:Cu,Cl phosphors prepared in various synthesis conditions were characterized by crystalline structure, particle size distribution and luminescent properties under UV excitation. Some ZnS:Cu,Cl sample phosphors were used to manufacture radioluminescent sources and their sensitivity of (beta) radiation was estimated. The optimum synthesis conditions were established.
