The optical property and phase transition of ZrV 2 O 7 were investigated by temperature‐dependent X‐ray diffraction, photoluminescence ( PL ), and Raman spectra. It was found that the material exhibited PL emission in the visible region. The temperature‐dependent PL emission showed that the peak energy for emission (at red wavelength) presented a red shift from 10 to 80 K, and then a blue shift with the increase in temperature. The PL emission bands of ZrV 2 O 7 shifted with change in temperature relating to its phase transition (80‐100 K), which could be confirmed by temperature‐dependent Raman spectra.
