Light Absorption and Structural Properties of TiO₂-AgCl Thin Films Doped with Cu by Sol-Gel Process

Abstract:

TiO₂-AgCl thin films doped with Cu were prepared by sol-gel and coated on glass slide by dip coating process. The prepared thin films were synthesized at the temperature of 400 ^◦C for 2 h with a heating rate of 10^◦C/min. The microstructures of synthesized thin films were characterized by XRD, AFM and SEM. Finally, the light absorption property was evaluated by UV-vis diffuse reflectance spectroscopy. The results show all samples have the thickness in range of 200-250 nm and surfaces are dense with a large surface area. It was found that Cu doping has an effect on light absorption and structure properties of the synthesized thin films. It can be noted that TiO₂-AgCl-5Cu thin films showed the highest light absorption (2.50%) under UV irradiation.
