摘要：化学方法合成了酞菁铜(CuPc)掺杂TiO2微腔,用傅里叶变换红外光谱、拉曼光谱研究了其的光谱特性,用X射线吸收精细结构(XAFS)谱分析了其的精细结构。结果显示,TiO2微腔被CuPc掺杂后,CuPc和TiO2之间发生了相互作用,使红外光谱出现了900.76cm-1的振动吸收峰;同时,在3392.75cm-1的OH振动和2848.83cm-1的CH振动发生了"红移";酞菁大环平面的C—C或C—N振动、苯环上C—H面内和C—N面外的弯曲振动也有一定的峰位移动和强度变化。在拉曼光谱图上,CuPc掺杂TiO2微腔中出现的403.4,592.1和679.1cm-1的TiO2的特征振动峰,但它们发生了波数移动,而在1586.8和1525.6cm-1出现的振动峰说明CuPc和TiO2形成了复合体,这些变化与酞菁铜的大环分子结构的平面取向有关。在XAFS上,CuPc掺杂TiO2微腔中的Ti呈现四面体TiO4的结构形式,TiO2的内层的中间距离和表面结构发生了变化。
Copper phthalocyanine-doped TiO2 microcavities were fabricated by chemistry method. Their spectrum characterization was studied by Fourier transform infrared （FTIR） and Raman spectroscopy, and their fine structure was analyzed by X-ray absorption fine structure （XAFS）. The results show that there is interaction of copper phthaloeyanine （CuPc） and TiO2 microcavities after TiO2 mierocavities was doped with CuPe. For example, there is absorption at 900. 76 cm^-1 in F-FIR spectra, and the ＂red shift＂ of both OH vibration at 3 392.75 cm-1 and CH vibration at 2 848. 83 cm-1. There exist definite peak shifts and intensity changes in infrared absorption in the C--C or C--N vibration in the planar phthalocyanine ring, the winding vibration of C--H inside and C--N outside plane of benzene ring. In Raman spectrum, there are 403.4, 592. 1 and 679. 1 cm^-1 characterized peaks of TiOz in CuPc-doped TiOz microcavities, but their wave-numbers show shifts to anatase TiO2. The vibration peaks at 1 586. 8 and 1 525.6 cm^-1 show that there exists the composite material of CuPc and TiO2. These changes are related to the plane tropism of the molecule structure of copper phthalocyanine. XAFS showed tetrahedron TiO4 structure of Ti in TiO2 microcavities doped with copper phthalocyanine, and the changes of inner ＂medial distances＂ and the surface structure of TiO2 microcavities.
