Abstract

ZnS:Cu, Br (0.005–0.01, 0.8 wt %) radioluminescent materials were synthesized for the first time from solid charge mixtures using a microwave sintering. The temperature range of zinc sulfide matrix recrystallization at microwave synthesis was determined in a range of 600–650°C. The microstructure and phase composition of the synthesized luminescent materials were studied; it was shown that at 650°C, a complete phase transformation of the ZnS matrix into a high-temperature wurtzite modification occurs. The spectral and brightness characteristics of tritium radioluminescence were obtained and compared with samples synthesized using a traditional solid-phase method.
