Commercial Ce 3+ : YAG phosphors were embedded in glass frits. Thermal condition for the viscous sintering of the composite materials was optimized. The phosphor–glass composites had maximum external efficiency of 30% and maximum light extraction efficiency of 39%. Color temperatures of the composites composed of fluorescent glass frits containing Eu 3+ and Mn 2+ combined with blue LED s shifted from ~7000 to ~4000 K.
