Abstract. Using the solid state reaction method, we synthesize the Ca0.88Al2Si2O8:Eu 2+ 0.12 phosphor powders at different sintering temperatures ranging from 1100 to 1500 o C. From XRay diffraction patterns, we confirmed that all the samples acquired mixed CaAl2Si2O8 (triclinic), CaAlO4 (Monoclinic) and SiO8 (Hexagonal) phases. For the Ca0.88Al2Si2O8:Eu 2+ 0.12 phosphors, the excitation spectra exhibited an unresolved broad band in the range from 200 to 420 nm and maximum intensity at 350 nm. The emission spectra of CaAl2Si2O8:Eu 2+ show broad band ranging from 400 to 560 nm and maximum wavelength is found to be at around 440nm, which can be ascribed to the electric-dipole-allowed 4f 6 5d 1 -8 S7/2(4f 7 ) transition of the Eu 2+ ions. The Commission International De I-Eclairage 1931 (CIE 1931) chromaticity coordinates for Ca0.88Al2Si2O8:Eu 2+ 0.12 phosphors are calculated and represented at (0.168, 0.144).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
