Abstract
对四方磷钇矿型结构的lnPS4系列化合物rAMAn光谱的研究表明,PS3-4阴离子的对称伸缩振动频率ν1随镧系收缩呈线性有规则增大,非四方晶系luPS4的ν1值明显偏离该直线,这种变化趋势与相应结构的变化一致。
 
The Raman spectroscopy study of LnPS 4 series compounds with tetragonal xenotime structure shows that the symmetrically stretching vibration Frequency ν 1 increases linearly with the lanthanide contraction, i.e., the decrease of the eFFective ionic radius r Ln 3+ .Moreover, the ν 1 Frequency For the non tetragonal LuPS 4 Falls ofF the line running through the corresponding values For the tetragonal phases.This tendency is consistent with their structural modiFications.
