Abstract： Sr3-xBaxSiO5:Eu light emitting diode（LED） phosphor was coated with tetraethylorthosilicate by the method of sol -gel. The morphology, water-resistance stability and temperature quenching performance of phosphor after surface treatment were investigated. The packaging application of phosphor was studied. The results show that the surface treatment has obvious influence on the particle morphology of silicate phosphor. The water-resistance stability and temperature quenching performance are greatly improved. The initial luminous efficiency of the phosphor increases about 3%. The decay of luminous efficiency degrades 3% after aging 1 008 h.
Keywords: surface treatment; light emitting diode; silicate phosphor
