A series of Eu-doped silicate phosphors was prepared in a microwave furnace using different charge mixture preparation methods. Synthesis parameters (time and power) were optimized to increase the yield and brightness of phosphors featuring with a “warm” white luminescence. The charge mixture prepared using sol-gel process provided phosphor with enhanced brightness compared with a solid phase preparation technique supposedly due to more uniform distribution and better introduction of the activator into the phosphor. White LED prototype was fabricated using synthesized phosphor.
