Romanov 2 2 ITMO University, Saint-Petersburg, Russia 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. http://pubs.sciepub.com/joe/5/1/2/joe-5-1-2.pdf phosphor-in-glass luminescence LED
