Abstract: n the recent years, phosphor coverted (pc) white light emitting diode (w-LED) has become a crucial and reliable lighting source. The most extensively used phosphor material employed in pc-wLED is the versatile yellow light emitting cerium-doped yttrium aluminium garnet, Ce3+:Y3Al5O12 (Ce:YAG) material. Here, the combination of blue light emitted by InGaN-GaN-based LED chip along with the down-converted yellow light (540 nm) emitted by Ce:YAG phosphor gives rise to the generation of efficient white light. Phosphor-in-glass (P-i-G) composites which are found to be efficient alternatives to phosphor-in-silicones structures are presented in this manuscript. The fabrication of P-i-G material through tape-casting and screen-printing methods are discussed and are critically reviewed. The mechanical and optical properties of the P-i-G samples prepared using the two methods (tape – casting and screen printing) are discussed.
