摘要： 高纯熔石英中掺杂TiO2可使其具有低热膨胀或无膨胀性及特殊的紫外吸收,以实现能量转换,提高红外发射率,因而对其结构研究已受到关注,我们曾用Raman光谱研究了其结构与光谱特性,本文用光电子能谱(ESCA)探讨不同TiO2含量的熔石英中网络缺陷与钛的配位结构变化。

Abstract: The photoelectron spectra of Ois, Sip,Ti2, of non-crystal TiO2-SiO2with various TiO2contents were obtained by ESCA. The relationship between their chemical shifts and the network defects, the titanium coordination structure was discussed. With increasing the content of TiO2up to about 7wt%, the quantity of the defects tends to saturation and the number of the Ti atoms in substitution state increases, comparing with that mainly in interstitial state at lower content of TiO2.
