红色荧光粉，讨论了煅烧温度、煅烧时间以及Eu

掺杂浓度对样品发光性能的影响。通过XRD、荧光光谱分别对样品的性能进行表征，结果表明：样品的晶相结构为"M-相（M-phase）"。在466 nm蓝光激发下，合成的荧光粉具有橙光（593 nm）和红光（612 nm）发射。发光强度随着煅烧温度的升高先增大后减小，最佳的煅烧温度为850℃。同时，随着煅烧时间的增加，发光强度先增大后减小，最佳煅烧时间为6 h。当Eu

掺入质量分数为2.5%时，样品的发光强度达到最大。Li

:Eu

red phosphor was synthesized by sol-gel method. The influences of the sintering temperature

the sintering time and the Eu

doping concentration on the luminous properties of the samples were discussed. The properties of the samples were characterized by X-ray diffraction(XRD) and photoluminescence spectroscopy

respectively. The results show that the samples are consist of "M-phase". Under the excitation of 466 nm

the orange emission at 593 nm and the red emission at 612 nm can be observed. The emission intensity increases with the increasing of the sintering temperature firstly and then decreases. The optimum sintering temperature is about 850℃. Moreover

the emission intensity increases with the increasing of the sintering time firstly and then decreases. The relatively high emission intensity of the sample can be obtained when the sintering time is 6 h. In addition

the optimal doping mass fraction of Eu

is about 2.5%. Therefore

the red phosphor has potential application in the white-LED field.
