Novel dual valence Eu-doped Ca₄ZrGe₃O₁₂ (CZGO) phosphors were successfully fabricated in air atmosphere through a solid-state route. Their crystal structure, photoluminescence properties as well as thermal quenching performance were investigated systematically. The spectra show that part of Eu³⁺ wer...
