In this study, a series of Gd $^{3 +}$ , Ce $^{3 +}$ 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 50nm to $1 μ$ m. Photoluminescence (PL) studies revealed that PL emission for Gd $^{3 +}$ and Ce $^{3 +}$ -doped Sr₂P₂O₇phosphor gives significant emissions which are suitable for application in UV-LEDs for phototherapy portable devices.
