| Abstract: | Green photoluminescent powder of aluminate strontium (cerium,terbium) is prepared by utilizing ceria,terdia and aluminate strontium. The result of experiment reveals that luminescent performance of specimen is mainly affected by the contents of cerium and terbium, and by thermal insulation. The luminescent mechanism of Ce 3+ and Tb 3+ is discussed preliminarily. |

| Keywords: | photoluminescent powder energy transmit cerium terbium optical spectrum sensitization |
