Abstract

Compositions of (CaSrBa) orthosilicate phosphors were prepared by Liquid Phase Precursor method. The structural phase determinations were done systematically by powder X ray diffraction and Transmission electron microscopy. The PL emission was observed under 450 and 375nm excitation and green-red and pure green emission was observed for the 4f⁶5d → 4f⁷transition of Eu²⁺ion. The luminescence nature of the samples is determined to vary with crystal field effect on the Eu²⁺ion and has been studied with the change in the binary Ca-Sr, Ba-Sr and ternary Ca-Sr-Ba compositions.
