摘 要: | Eu^2 -aetivated strontium choloro-phosphate has been used for lamp phosphor traditionally with high efficiency. In this paper, the cathodoluminescent properties of Sr5(PO4)3Cl:Eu^2 have been investigated for application in field emission display. The influence of Ba^2 , Ca^2 impurities on the cathodoluminescent spectrum of Sr5(PO4)3Cl:Eu^2 has also been measured. When operate voltage varied from mid- to low-voltage, the relative brightness and saturation behavior of phosphor was observed at different current density.
