red phosphor was synthesized by sol-gel method. The influences of the sintering temperature
the sintering time and the Eu
3+
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.
