摘要：

Single crystals of yttrium fluoride YF3 have been grown by the Czokralski method and studied by Raman scattering in the temperature range 20 K - 730 K. The results are consistent with the prediction of the group theory analysis in the framework of the space group Pnma (7 Ag + 5 B1g + 7 B2g + 5 B3g) although two lines B2g are missing.There is no evidence for any structural phase transition in this temperature range. The structural relationship between the phase investigated and the high temperature phase (out of the temperature range studied) is discussed.
