摘要
本文报导了掺镨四硼酸铝钇［ＰｒｘＹ１－ｘＡｌ３（ＢＯ３）４，简称ＰＹＡＢ］的偏振拉曼光散射。得到了不同几何配制下的Ａ１和Ｅ振动模。讨论了由于ＰＹＡＢ特殊的结构，使ＹＯ４、ＢＯ３等基团的内振动模偏离自由基团的振动频率及ＡｌＯ６八面体内振动模劈裂的原因。
The polarized Raman scattering of praseodymium doped yttrium alumium tetraborate [ PrxY1 - xAl3 (BO3 )4, abbreviated to PYAB] was reported. Various vibration modes of A1 and E were obtained under different experimental geometries. The reasons that the deviation of internal modes of YO4 from vibration frequencies of free group and the splitting Of vibration modes in the AlO6 octrahedra were discussed.
