| Abstract: | This paper reports the fluorescence properties of a new series of (La, Zn) OF:Sm3+ powder phosphors. The measured fluorescence spectra were analyzed by computing the color coordinates and relative fluorescence intensity ratios (ED/MD). A bright yellowish-orange color was observed from these powder phosphors under a UV-source due to the confirmation of the transitions 4G5/2→6H5/2, 4G5/2→6H7/2, and 4G5/2→6H9/2. Scanning electron microscopic studies were performed to understand the average grain size of the synthesized powder phosphors. |
