Abstract In the present study, novel hexagonal GdInO3:Eu3+ red phosphors were prepared by a high-temperature solid-state method. Their phase composition, microscopic morphology and luminescence properties characterized using X-ray diffraction, scanning electron microscopy photoluminescence spectroscopy. The results indicated that crystal structure of matrix material was unaffected doping different concentrations Eu3+. existed as irregular micro-sized polyhedra. They emitted 630 nm light when excited 395 ultraviolet 467 blue sources. optimal content Eu3+ found to be 0.07 corresponding color coordinates GdInO3:0.07 phosphor (0.6426, 0.3510), with fluorescence lifetime 1.839 ms activation energy (ΔE) 0.15 eV. A white light-emitting diode (LED) mixing this commercially available green phosphors, which exhibited remarkable emission. chromaticity device (0.3638, 0.3481) rendering index 83.5. demonstrated is good material, can utilized in LEDs.
