摘要：

Eu3+-doped Ca2InTaO6 phosphors were synthesized by a high-temperature solid-state reaction. Their crystal structure, composition, phase purity, photoluminescence (PL) properties, and thermal quenching me-chanism were investigated in this experiment. The band gap of Ca2InTaO6 (3.87 eV) classifies it as an in-direct band gap material. X-ray diffraction results confirm the good phase purity of the synthesized material has good phase purity. The Ca2InTaO6 lattice has an orthorhombic structure, which includes the Pnma(No. 62) space group. After being excited at 395 nm, Ca2InTaO6:0.40Eu3+ phosphor s...
