| Abstract: | Use Ti（SO4）2 as the raw material and anhydrous sodium carbonate（Na2CO3） as the additive,TiO2 thin films are prepared by using the method of hydrothermal synthesis on the substrate of titanium successfully.The law of concentrations effect on the growth characteristics of titanium dioxide thin film、the crystallization and phase composition has been studied systematically by using the method of X-ray diffraction（XRD） and Scanning electron microscopy（SEM）,the dynamics mechanism has been analyzed;The excitation characteristics of prepared TiO2 thin films has been studied by using photoluminescence spectroscopy（PL）,and the laws of effect has been theoretical explained through the micro-mechanism. |
