Development of plasma display panel phosphors at National Physical Laboratory, New Delhi

摘要

Plasma Display Panel (PDP) phosphors of three primary colours red, green and blue (RGB) have been developed for application in 50” HDPDP panel at SAMTEL. Three phosphors one each for red, green and blue was zeroed down. Synthesis processes by high temperature solid state reaction were optimized to achieve maximum quantum efficiency. We have also synthesized RGB nanophosphors by autocombustion method and compared with bulk RGB phosphor. Photoluminescence emission characteristics under VUV (172 nm) and UV (250 nm) excitation of the RGB phosphors show their suitability for PDP applications.
