Abstract
In this study, a series of Gd[Formula: see text], Ce[Formula: see text] doped Sr2P2O7 phosphors synthesized by a novel method utilizing stearic acid sol–gel are reported. Structural analysis performed by X-ray diffraction (XRD) pattern revealed that doping of trivalent lanthanide ions did not change the orthorhombic structure possessed by Sr2P2O7 matrix and also confirmed the phase purity and crystallinity of the phosphor. Scanning electron microscopy (SEM) micrograph confirms its surface morphology and particle size in the range of 50[Formula: see text]nm to [Formula: see text]m. Photoluminescence (PL) studies revealed that PL emission for Gd[Formula: see text] and Ce[Formula: see text]-doped Sr2P2O7phosphor gives significant emissions which are suitable for application in UV-LEDs for phototherapy portable devices.
