Abstract
Single phased CaSrAl2SiO7 phosphor singly doped with different concentrations of trivalent cerium and terbium; and co-doped with varying Tb3+ concentration were prepared by standard solid state reaction (SSR) method. The crystallinity and particle morphology of the product samples were analysed by using XRD and TEM characterizations. Photoluminescence characterizations of singly doped and co-doped samples were studied in detail. CaSrAl2SiO7:Ce3+,Tb3+ phosphor exhibit a broad blue emission band at 410 nm and some sharp emission bands in blue green and yellow regions, which originate from Ce3+ and Tb3+ ions, respectively. By increasing the concentration of Tb3+ ions while fixing Ce3+ concentration in the host lattice energy transfer takes place from Ce3+ to Tb3+ ions which create luminescence emission in white region. CaSrAl2SiO7:Ce3+,Tb3+ phosphors are proved to be promising candidates for white lighting for outdoor illumination.
