- 論文の詳細を見る
Ca3Sc2Si3O12:Ce3+ phosphor was synthesized by what we have named Emulsion–Evaporation (EE) method, where W/O emulsions of metallic ions and precipitants were mixed and condensed in a rotary evaporator. The EE-derived precursor was amorphous below 600°C and directly crystallized to CSS above 800°C without passing any impurity phases. SEM/EDS and 29Si-NMR analyses revealed that the EE process is superior in achieving homogeneity. Ca3Sc2Si3O12:Ce3+ phosphor fired at 1350°C showed higher fluorescent emission than those prepared by a normal precipitation (PP) without EE route and by a solid state (SS) synthesis.
