Abstract：Doubly doped YAG∶Ce3+, Pb2+ phosphor was obtained by doping YAG∶Ce3+ phosphor with PbO. Compared with the emission spectra of YAG∶Ce3+ phosphor without PbO, the Ce3+ emission band of YAG∶Ce3+, Pb2+ shifts to longet wave, which can enhance the red component of spectrum. Meanwhile, the intensity of Ce3+ emission is increased by 10% when the concentration of PbO is 5%, SEM image indicates that PbO may act as a flux. Temperature-dependent emission spectra of YAG∶Ce3+, Pb2+ phosphor show a better thermal quenching characteristics than YAG∶Ce3+ phosphor.
Key words：YAG;PbO;Enhanced red component;Emission intensity
