SrCO3∶Eu2+荧光粉的制备及其发光性能研究
Synthesis and Luminescence Properties of SrCO3∶ Eu2+ Phosphor
摘要
Abstract
SrCO3: Eu3 + precursor was synthesized through microwave asssisted co-precipitation method, then the SrCO3: Eu2+ phosphor was obtained by high temperature reduction process. The structure and luminescence properties of the SrCO3 = Eu2 + were analyzed by XRD and PL-PLE. The results showed that the best sintering temperature was 1100 t and the optimum content of boric acid was 15% . In addition, the excitation spectrum of the SrCO3: Eu + phosphor was consisted of two broad bands at 220-320 nm and 400-580 nm, and the emission spectrum was located at 550-700 nm. It characteristic emission peak was at about 610 nm (Aex =475 nm) , which belong to red fluorescence. This strontium carbonate matrix phosphor which have broadband excitation and emission could be used for manufacturing fluorescent glass.关键词
