Abstract

The temperature-dependent Raman studies of Pr2Zr2O7 has been performed on single crystals samples in the temperature range from 80 K to 820 K. By using polarization measurement, the vibration modes of A1g, Eg, and 4T2g have been assigned on 295.9 cm-1, 497.3 cm-1, and 102.4 cm-1, 309.2 cm-1, 670.6 cm-1, 878 cm-1, respectively. The ambiguity vibration mode around 300 cm-1 in pyrochlore compounds can be resolved. The 380 cm-1 mode showed sharpening upon heating up from 370 K which support the present of Oxygen distortion towards vacant site. © Published under licence by IOP Publishing Ltd.
