Abstract
A liquid glass-based phosphor material for white light-emitting diodes (LEDs) is proposed. The material is based on sodium silicate (Na2SiO3) matrix with embedded microparticles of cerium-doped yttrium aluminum garnet (YAG:Се3+). The technique for the material synthesis is described. The results of investigation of the optical and thermal characteristics of the material and a white LED module with a primary optic element made of the material are presented. Advantages of the developed phosphor material for primary optics applications in high-power LED modules as compared to commercial silicone are demonstrated.
