摘要：

采用高温固相法合成了BaZnP2O7∶Eu3+荧光粉, 并对其发光性质进行了研究.

关键词: 发光二极管(LED), 荧光粉, Eu3+, 磷酸盐

Abstract: BaZnP2O7∶Eu3+ phosphor was synthesized by a high temperature solid state reaction. The compound shows four major emission peaks locating at 588, 613, 622 and 654 nm that correspond to the 5D0-7F1, 5D0-7F2 and 5D0-7F3 typical transition of Eu3+, respectively. The influence of the concentration of Eu3+ ions on the emission intensity was investigated and the concentration quench did not occured. The role of charge compensation of Li+, Na+ and Cl- ions to the emission intensity was also studied. It was found that Li+ ions gave the best improvement to enhance the intensity of the emissions. The results show that BaZnP2O7∶Eu3+ red-emitting phosphor is very suitable for white light emitting diode(w-LED) based on UV InGaN chip.

Key words: Light emitting diode(LED), Phosphor, Eu3+, Phosphate
