纳米TiO_2薄膜的拉曼光谱

The Raman Spectra of TiO_2 Nano Thin Films

本文测量了纳米TiO2 薄膜的Raman散射谱 ,并用B1g模计算了不同厚度的纳米TiO2薄膜的粒度。结果表明 ,随着膜厚的增加 ,粒度也在增加 ,膜厚达到一定程度后 。

In this paper we have studied the Raman spectra of the TiO 2 nano thin films, and calculated the samples average size with different thickness by the Raman shift of B 1g The experiment results showed that, with the increase of thickness, samples size increase, when the thickness reached a cetain extent, samples size increased slowly
