Abstract

Abstract: The optical absorbance of metal ion doped TiO₂ nanoclusters in UV and visible region was determined at room temperature. The optical absorbance of TiO₂ after doping metal ions increased considerably and a red shift of the band-gap took place. A nonlinear relationship is shown between the absorbance change and wavelength.

Key words: metal ions, TiO₂ nanoclusters, optical absorbance

摘要： 实验测量掺杂不同金属离子的TiO₂纳米晶簇在UV和可见波段的室温光吸收谱。金属离子掺杂明显增强TiO₂纳米晶簇的光吸收。TiO₂带隙发生红移。光吸收增加量随波长非线性变化。
