摘要：

A novel perovskite phosphor CaZrO3 co-doped with Eu3+ and Gd3+ ions was prepared by a high-energy deformation process. The structures, morphologies, compositions, and photoluminescence properties of the materials were systematically measured and studied. The X-ray diffraction patterns showed an orthorhombic perovskite crystal structure. The highest excitation peak was observed at 394 nm, which is in good agreement with the near-UV chips. The prepared phosphors excited by near-UV 394 nm light exhibit narrow-band red emission dominated by the 5D0 → 7F2 transition of Eu3+, which peaked at 614 nm. The optimum concentration of Gd3+ in the CaZrO3: Eu3+, Gd3+ phosphor was 2 mol%, above which concentration quenching was observed. According to the results of the luminescence properties, the prepared phosphor materials have potential as efficient candidates for near-UV and blue light-emitting diode chips and as efficient components for the manufacture of white light-emitting diodes. © 2025
