    利用磁控溅射方法制备了纳米TiO2薄膜,通过Raman光谱和UV-Vis光谱讨论了TiO2薄膜的带宽随着厚度变化的规律.随着薄膜厚度的增加,TiO2薄膜的带宽变窄,这是由于纳米薄膜的纳米效应所致.

    The TiO2 films were prepared on Si (100) substrates by RF magnetic sputtering PVD. The bandgap width of nanometer TiO2 thin films was investigated by using Raman spectra and Ultraviolet-visible (UV-Vis) Spectra. The bandgap width of TiO2 thin films narrows with the increase of thickness due to nano-effects of nanometer thin films.
