phosphor was synthesized by hightemperature solidstate reactions and investigated by photoluminescence excitation

emission spectroscopies and lifetime. The excitation and emission spectra showed that the phosphor could be efficiently excited by the incident light of 300~450 nm

well matched with the emission band of 395 nmemitting InGaN chip

and emitted an intense orange light. The fluorescence lifetimes values of Eu

ion were determined to be 1.53 μs and 7.29 μs

respectively. By combining the phosphor with a 395 nmemitting InGaN chip

an intense orange LED was fabricated. Under 20 mA forwardbias current

its CIE chromaticity coordinates were (0.533

0.446). The result showed that hightemperature phase Ca
