New types of phosphor (YAG:Ce3+: yttrium–aluminum garnet doped with Ce3+ ions) containing glass-ceramics material was developed for light-emitting diodes (LEDs). The optical properties of the experimental samples were investigated and are reported on. Use of new phosphor material in white LEDs fabricated with the “chip-on-board” technology is demonstrated.

Key words: glass-ceramics, phosphor, luminescence, energy saving, white light-emitting diode, fluorescence
