The Raman spectrums of new scintillation materials LaCl3 and LaBr3 single crystals in different temperatures for different surfaces are measured. Five of all six peaks of LaCl3 crystal and all six peaks of LaBr3 crystal are obtained. The Raman shift becomes smaller while temperature rises,and approximately can be fit to a linearity result. A polarizer is placed on the path of Raman scattering light,and no change can be observed while light propagates parallel to c-axis,while remarkable changes can be observed when light propagates perpendicular to c-axis.
