Bi(Pb)-Sr-Ca-Cu-O超导体红外吸收谱的分析

Characteristics of Infrared Absorption Spectrum of Bi(Pb) Sr Ca Cu O Superconductor

测试了Ｂｉ（Ｐｂ）ＳｒＣａＣｕＯ超导体的红外吸收光谱，在４００～４０００ｃｍ－１波段内发现５个吸收峰．分析认为它们与ＣｕＯ键振动，Ｐｂ掺杂的Ｂｉ（Ｐｂ）ＣｕＯ键沿Ｃ轴的伸缩振动。

Infrared absorption spectrum of Bi system high Tc superconductor was analyzed in this paper. The results show that five absorption peaks existed at the 400～800cm -1 frequency range, and these absorption peaks were related with stretching vibration of Cu O bond and Bi(Pb) Cu O bond along C axis, as well as O hole in structure of Bi system superconductor.
