초록
The synthesis of Ca0.92AlSiN3 : 0.08Eu2+ (CASN : Eu) phosphor was investigated by a carbothermal reduction and nitridation (CRN) reaction using a liquid-phase precursor (LPP) method. The carbon source for CRN reaction was prepared by a precursor of the LPP method, and carbonization of the precursor was carried out at 300 o C. CASN : Eu phosphor was constructed through the CRN reaction at synthesis temperatures of 1500 and 1600 o C. The obtained CASN : Eu phosphors were of a mixed powder with AlN. The main emission spectra of the CASN : Eu phosphors were located at 630 nm, and the main excitation spectra were in the range of 370-470 nm.
