Paper Abstract

In this paper, LaxNd1-xPO4(x=0, 0.5, 0.8) series crystals with high Nd-concentration were grown through a seed-inducing method using Li2CO3-2MoO3 as a flux, and some factors influencing the quality of crystals were also discussed. The IR, absorption and fluorescence spectra of La0.5Nd0.5PO4 crystals at room temperature were measured. High temperature X-ray diffraction was conducted to investigate the thermal expansion behavior of NdPO4 crystals in the temperature range from 25°C to 900°C. Abnormal diffraction peaks shifts were observed along the (200) and (020) direction. The results indicate that as temperature increased, the crystal in the (200) and (020) direction contracted (from 25 °C to 700 °C) at first, and then expanded (from 700°C to 900°C). The mechanism responsible for the abnormal thermal expansion in NdPO4 was attributed to the existence of rigid unit modes (RUM).
