Abstract
Abstract The photoluminescent properties of un-doped and Sm 3+ doped Ca 3 Y 2 Si 3 O 12 phosphors were prepared by the citrate sol-gel method. Un-doped sample has shown a strong blue emission, which has its maximum intensity at 389 nm. Among all the observed emission transitions 4 G 5/2 → 6 H J (J = 5/2, 7/2 & 9/2) of Sm 3+ , the reddish-orange (RO) emission transition 4 G 5/2 → 6 H 7/2 is more prominent, which matches well with the emission wavelength of near UV (n-UV) LED. The reasons for the observance of such prominent visible color emissions from these phosphors have been substantiated appropriately. Besides, structural details of these samples have also been analyzed from the measured XRD, TEM, TG-DTA and FT-IR profiles.
