摘要
利用溶胶－凝胶方法，研究了Ｃ６０在ＫＨ—５６０基Ｏｒｍｏｓｉｌｓ（ＯｒｇａｎｉｃＭｏｄｉｆｉｅｄＳｉｌｉｃａｔｅｓ）中的掺杂过程．采用紫外激发的室温荧光光谱和Ｒａｍａｎ光进分析研究Ｃ６０在有机改性硅酸盐材料中的结构状况．可能因为Ｃ６０受到环境的影响，两个Ｒａｍａｎ峰２７０和１４５９ｃｍ－１分裂成另外一些峰．与基质作品相比，Ｃ６０掺杂样品在２１９ｎｍ紫外波长激发的荧光光谱明显不同，发现有６２０，６７０，６８２，７１５，７３４和７６６ｎｍ六个发光峰．其中６８２，７１５和７３４ｎｍ的三个发光峰与低温态（５Ｋ，２０Ｋ）文献值相近．
The Raman and photoluminescence spectra of C60-doped in Ormosils have been recorded at room temperature. The Raman spectra of C60-doped Ormosils is similar to that of the substrate on profile,but different in the details. Three scattering peaks of C60 at 270, 497 and 1459cm-1 are splitted to some peaks. The photoluminescence spectra of C60-doped Ormosils at room temperature is obviously different from that of the substrate. Six peaks at 620, 670, 682, 715, 734 and 766nm are seperately distincted from the spectrum when λexe=219nm. The peaks of 715 and 734 nm agree with the luminescence of C60 at 5K in glassy toluene.
