Abstract
The influence of processing conditions, such as time and temperature, and the effect of fluxing agents on the particle size and concomitant properties observed during zinc sulfide phosphor preparation are reported. The particle size increases exponentially with the reciprocal firing temperature and as the square root of the firing time when phosphors are prepared in open boats; the activation energy and frequency constant depend on the flux employed. A particle size anomaly is observed when zinc sulfide powder containing zinc chloride is processed near 1000°C in sealed quartz vials. This anomaly, which can be ascribed to the Hedvall effect, is accompanied by anomalies in chloride retention and crystal structure.
