Paper Abstract

Silver and copper double activated phosphor samples were synthesized from zinc sulphide prepared by thiosulphate method and with a NaCl-MgCl2 mixture as flux. The thermal treatment was performed in a protective atmosphere at 900 - 1100 degree(s)C. The samples were characterized by crystalline structure (XRD patterns) and luminescent properties (emission spectra, decay curves). An intensification effect of the copper green fluorescence by silver ions was put in evidence. Conditions for a good green emitting phosphor were established.
