| 摘 要： | 利用拉曼散射和红外吸收光谱研究了Ｙ１－ｘＮｄｘＳｒ２Ｃｕ２．７Ｍｏ０．３Ｏ７－δ（ｘ＝０，０．２，０．５，０．８，１．０）系列样品的声子振动性质。实验结果表明，对ｘ＝０的样品，在拉曼光谱中主要出现３２３，４４３，５２２和５７８ｃｍ－１几个特征峰，在中红外吸收光谱中出现５２２，５８０和６４６ｃｍ－１特征峰。随着样品中Ｎｄ组分的增加，３２３ｃｍ－１峰向低波数发生位移，而５２２和６４６ｃｍ－１峰则向高波数发生位移。本文对这些振动模进行了指认，并对其随不同样品组分的变化行为进行了讨论

| Abstract: | the phonon vibration characteristics of the series of Y 1-x Nd xSr 2Cu 2 7 Mo 0 3 O 7-δ samples (x=0,0 2,0 5,0 8,1 0) were studied by using Raman spectroscopy and infrared absorption spectroscopy. The typical phonon vibration modes were observed at 323、443、522、578 and 646cm -1 . The 522 cm -1 and 646cm -1 peaks move to higher wavenumber and the 323cm -1 peak moves to lower wavenumber with increasing Nd content x. In this paper, these phonon modes were assigned and their variation behavior with increasing Nd content x were discussed. |
