Abstract
A series of KCaPO4:Eu3+ phosphors was effectively synthesized utilizing a wet chemical method. The photoluminescence excitation and emission properties of the phosphor were investigated. The KCaPO4:Eu3+ phosphor was efficiently excited at 394 nm, and the PL (Photoluminescence) emission spectra were obtained at 591 and 614 nm. Concentration quenching occurred at a Eu3+ ion concentration of 0.5 mol%. The present work suggests that the KCaPO4:Eu3+ phosphors may be a potential candidate as a near-UV (Ultraviolet) convertible material for solid state lighting applications.
