Abstract

TiO2 thin films were prepared on quartz glasses by pulsed laser deposition (PLD) using a KrF laser excimer. The crystalline structure was characterized by X-ray diffraction, and the optical properties of the films were investigated using spectroscopic ellipsometry and UV-vis spectra respectively. The effects of the PLD conditions, including substrate temperature and O2 pressure on the crystalline structure and the optical properties of the films were investigated. The results indicated that there are a suitable substrate temperature and an O2 pressure which is favorable for the synthesis of anatase-type TiO2.
