In this project, we examined the usefulness of Raman spectroscopy as a tool of characterization of inorganic materials. In the first, it was shown that the vibrational spectra of industrial glass materials for manufacturing optical fibers, to which several compounds were added as dopants. It was proved that the changes in wavenumbers or band shapes for the Raman bands of quartz glass were realized, or not realized according to the kind of dopants. For example, the wavenumbers and band shapes showed the marked change in the case of <B_2O_3> as a dopant, while no such changes were not observed in the case of fluorine dopant. This phenomenon suggested that there are some cases where the structure of glass materials changes as a result of mixing dopants. The measurement of optical fibers whose lengths are from 10 m to 1 km was successfully made by entering the excitation laser beam into one end of fibers, and measuring spectrally the light coming from the other end of fibers. There are som … More e cases where the spectra of fibers are different from those of glass materials. We consider that the process of manufacturing fibers is responsible for such spectral difference. In the next, we examined boron nitride with Raman spectroscopic method. The samples are all black powders, and the measurement for these samples succeeded by making tablets after the samples are diluted with KBr powders, and rotating the tablet with high speed. It was proved that each boron nitride of hexagonal, cubic and wurzite type exhibited characteristic Raman spectral patterns. Especially, in the case of the sample of wurzite type, no Raman signal was observed in the Raman spectrum, while the two clear bands appeared in the infrared absorption spectrum. That is, the exclusion principle was realized exactly. This phenomenon may give important informations for the structure of this sample. Lastly, we designed to equip a microscopic Raman measurement instrument with the Raman spectrophotometer used till now. By use of this instrument, it was confirmed that the sensitivity in the case of the measurement of the inside of optical fibers (the core parts) increased remarkably. At the same time, it is considered very important that by use of the microscopic technique, the part of fibers, which is being measured, can become clear. Less

在这个项目中，我们研究了拉曼光谱作为表征无机材料的工具的有用性。在第一，它表明，振动光谱的工业玻璃材料制造光纤，其中添加了几种化合物作为掺杂剂。结果表明，石英玻璃的拉曼谱带的波数或谱带形状随掺杂剂种类的不同而发生或不发生变化。例如，波数和能带形状在作为掺杂剂的情况下显示出显著的变化<B_2O_3>，而在氟掺杂剂的情况下没有观察到这样的变化。这一现象表明，在某些情况下，玻璃材料的结构会因掺杂剂的混合而发生变化。通过将激发激光束入射到光纤的一端，并对来自光纤另一端的光进行光谱测量，成功地实现了长度为10 m至1 km的光纤的测量。有一些 ...更多信息 纤维的光谱不同于玻璃材料的光谱。我们认为，制造纤维的过程是负责这种光谱差异。其次，我们用拉曼光谱法对氮化硼进行了研究。样品均为黑色粉末，用KBr粉末稀释后压片，高速旋转压片，测定成功。结果表明，六方氮化硼、立方氮化硼和六方氮化硼均具有特征性的拉曼谱图。特别是纤锌矿型样品的拉曼光谱中没有观察到拉曼信号，而红外吸收光谱中出现了两个清晰的吸收带。也就是说，不相容原理被准确地实现了。这一现象可能为该样品的结构提供重要的信息。最后，我们设计了一个显微拉曼测量仪器，配备了目前使用的拉曼分光光度计。通过使用该仪器，证实了在测量光纤内部（芯部）的情况下的灵敏度显著增加。同时，它被认为是非常重要的，通过使用显微镜技术，纤维的一部分，这是被测量，可以变得清晰。少
