| heal.abstract | Novel Eu2+-doped Ca2AlSi3O2N5 phosphors with a general formula of EuxCa2-xAlSi3O2N5 were successfully prepared via a solid-state reaction method under a nitrogen atmosphere. The produced phosphors were effectively excited by UV-vis light in the wavelength range between 250 and 400 nm, and featured an intense green emission band which peaked at about 500 nm. The emission spectra featured a red-shift over increasing Eu2+ content and the temperature of heat treatment. The maximum intensity of emission was obtained for x = 0.014 and heat treatment at 1450 degrees C. The photoluminescence properties of the produced Ca2AlSi3O2N5:Eu2+ phosphors qualify them for consideration in potential use as green phosphors in UVLED-based white LED. (C) 2012 Elsevier B.V.
