Abstract
Eu-doped strontium halophosphate phosphor particles were first prepared by spray pyrolysis from various types of precursor sources and their luminescence characteristics were investigated. Phase-pure halophosphate particles were obtained when ammonium phosphate and ammonium dihydrogen phosphate were used as phosphorous source, while halophosphate particles were not obtained using phosphoric acid. Spherical and nonaggregated particles were obtained when ammonium phosphate and ammonium dihydrogen phosphate were used. However, the particles prepared from phosphoric acid were strongly aggregated. The particles prepared from the mixture of strontium nitrate and strontium chloride as strontium and chlorine sources, had a spherical shape and are nonaggregated. The particles prepared from strontium nitrate, strontium chloride and ammonium dihydrogen phosphate had the highest PL intensity among halophosphates due to their phase purity and spherical morphology.
