Abstract

Eu2+ activated phosphors with the composition of Ca013Sr0.87Al2Si2O8 were synthesized by combustion technique. The luminescent properties of these phosphors have been explored by analyzing their excitation and emission spectra with the help of photoluminescence (PL) spectroscopy. The phase-forming processes and presence of associated mode of vibrations of the phosphors were studied by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) respectively. Under ultra-violet (UV) excitation, Ca013Sr0.87Al2Si2O8 phosphors had broad emission spectrum between 418 and 550 nm in the blue-green region of spectra corresponding to 4f65d→4f7 transition of Eu2+ ion. The results show Ca013Sr0.87Al2Si2O8: Eu2+ is a promising host candidate for the phosphors and can be used for improving the efficiency and quality of phosphor-converted white light-emitting diodes.
