| 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. |
