Paper Abstract
As a fine material widely used in solar cells, electrochromic devices and an excellent photocatalyst, Titanium dioxide
(TiO2) has attracted more and more attention. There are many factors that affect the properties of TiO2 thin films
including reaction temperature, reaction time and concentration. The influence of the pH of the precursor solution on the
formation of TiO2 thin films, however, has not been studied thoroughly. Involved in the solution such as Hydrochloric
acid (HCl) or urea ((NH2)2CO) reagent, the pH of the solution can be controlled by the ratio of both. During the
experiment, which involves the hydrolysis reaction of Ti3+, changing the pH of the solution will affect the speed of the
reaction rate and film thickness. Therefore, the pH of the solution affects the surface morphology of the TiO2 thin films.
The growth of TiO2 with different pH shows unequable states. Through the observation and characterization of the
experimental results, we can optimize the pH of the growth environment.
