Abstract

A luminescent composite material based on YAG:Ce3+–doped silicate glass (Phosphor-in-Glass, PiG) was fabricated and studied. For the glass matrix, the 40SiO2–25PbF2–20PbO(Pb3O4)–15AlF3 material was used. PiG samples were sintered at the temperature 550°C with concentration of YAG:Ce3+ varying from 90% down to 50%. Luminescence spectra of the PiG samples were recorded and quantum efficiency of the experimental samples was measured with the use of an integrating optical sphere. A design of light-emitting diode (LED) modules with the sintered PiG was developed and the temperature of the surface of the modules was analyzed.
