Abstract
In this study, different samples of Si and Sr co-doped TiO2 thin films (5 mol% Si and 5-10-15-20 mol% Sr) were prepared via simple sol–gel synthesis method by using strontium acetate as strontium precursor, tetraethoxysilane as silicon precursor, and titanium (IV) isopropoxide (TTIP) as titanium precursor. The effects of co-doping process on the structural, optical, and wettability properties of thin films were studied by X-ray diffraction (XRD), Scanning electron microscope (SEM) and contact angle measurement. XRD results showed that, the anatase phase formation was promoted by Si+4 and Sr+2 co-doped TiO2 samples at higher percentage of Sr.Accordingly, the titania thin films showed various water contact angles, the water contact angles first decreased from 55.1° to 8.1° then increased to 40.7° by changing the content of Sr dopant from 5 to15 mol% and then to 20% mol.
