Abstract：The hydrolysis behavior of LED silicate green powder was studied. The silane coupling agent KH560 was used as coating reagent to coat silicate phosphor. The phase composition,microstructure and water resistance were characterized by SEM,XRD,and FS. The results indicate that the water resistance and stability of rare earth silicate phosphor have been improved well after coated,and that the luminous efficacy of coated phosphor LED have slight improvement.
