Using La(NO3)3·nH2O and H3BO3 as raw materials (oxidant),C2H5NO2,C8H8O7,C8H8O7(NH4)3 and CH4N2O as burning agents (reducing agents) and Yb(NO3)3·5H2O as modifier,LaBO3∶Yb3+ powders were prepared by solution combustion method.The products were analyzed and characterized by XRD,SEM and PL.The effects of different burning agents on the morphology and luminescence intensity of LaBO3∶Yb3+ powders were probed.The results shown that the crystallinity of the samples synthesized with C2H5NO2 and CH4N2O as burning agents was 99.7% and 100.0%.The crystallinity of samples synthesized with C8H8O7 and C8H8O7(NH4)3 as burners was 96.0% and 98.5%.The morphologies of the four products were quite different.The luminescence intensities of the powders synthesized with different burning agents were C2H5NO2,C8H8O7(NH4)3,C8H8O7 and CH4N2O in turn from high to low.
