A new fluorescence band at about 1930cm-1 has been observed in the FT-Raman spectra of some bioceramics. While a fluorescence band at about 760cm-1 has been already reported in the FT-Raman spectra of hydroxyapatite and related calcium phosphates, this new band is observed for the first time. This strong band is totally absent in the anti-Stokes side of the FT-Raman spectra and therefore has been assigned as a laser induced fluorescence band. It has been concluded that in recording FT-Raman spectra of minerals, all precautions about fluorescence bands should be considered, otherwise the FT-Raman spectra may well be misinterpreted.
在一些生物陶瓷的傅里叶变换拉曼光谱中观察到了一条位于约1930cm-1处的新荧光带。虽然在羟基磷灰石和相关磷酸钙的傅里叶变换拉曼光谱中已经报道过一条位于约760cm-1处的荧光带，但这条新带是首次被观察到。在傅里叶变换拉曼光谱的反斯托克斯侧完全没有这条强带，因此它被认定为激光诱导荧光带。得出的结论是，在记录矿物的傅里叶变换拉曼光谱时，应考虑到关于荧光带的所有预防措施，否则傅里叶变换拉曼光谱很可能会被误判。
