The present work reports on the synthesis of Terbium (Tb) doped KAlPO4Cl phosphors by the combustion of metal nitrates and urea carried out in a muffle furnace at a temperature of 650 °C. The powder phosphor samples obtained after combustion were characterized for structural and morphological analysis. Upon excitation with ultraviolet light of 380 nm, KAlPO4Cl doped with trivalent terbium ions exhibited strong emission in green light region with a weak emission in blue region which is very close to NUV region emission peaks situated at 544 nm and 551 nm. The emission spectrum reveals the potential of KAlPO4Cl:Tb3+ phosphor for LED as well as W-LEDs.
