Their phase composition, microscopic morphology and luminescence properties were characterized using X-ray diffraction, scanning electron microscopy and photoluminescence spectroscopy. The results indicated that the crystal structure of the matrix material was unaffected by the doping of different concentrations of Eu 3+ . The GdInO 3 :Eu 3+ phosphors existed as irregular micro-sized polyhedra. They emitted 630 nm red light when excited by 395 nm ultraviolet and 467 nm blue light sources. The optimal doping content of Eu 3+ was found to be 0.07 and the corresponding color coordinates of GdInO 3 :0.07 Eu 3+ phosphor were (0.6426, 0.3510), with a fluorescence lifetime of 1.839 ms and activation energy (ΔE) of 0.15 eV. A white light-emitting diode (LED) was prepared by mixing this red phosphor with commercially available blue and green phosphors, which exhibited remarkable white light emission. The chromaticity coordinates of the prepared device were (0.3638, 0.3481) with a color rendering index of 83.5. The results demonstrated that GdInO 3 :Eu 3+ is a good red light-emitting material, which can be utilized in white LEDs. high-temperature solid-phase method blue-light excitation GdInO3:Eu3+ photoluminescence Full Text Cite Share Download PDF Status: Published Journal Publication published 25 Jun, 2025 Read the published version in Chemical Papers → Version 1 posted Editorial decision: Accept 27 May, 2025 Reviewers agreed at journal 28 Apr, 2025 Reviewers invited by journal 28 Apr, 2025 Editor invited by journal 26 Apr, 2025 Editor assigned by journal 25 Apr, 2025 First submitted to journal 22 Apr, 2025 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
