Effect of Heat Treatment on Optical Properties of Cold Spray TiO2 Coated Glass
The cold spray TiO2 thin films were deposited on 5mm-thick float glass substrates using the sol containing nano-anatase TiO2. The effects of different heat treatment temperatures on optical properties were discussed. The properties of xerogel powder were analyzed using TG-DSC, the morphology and structure of TiO2 thin films were characterized by FESEM and XRD, the transmittance and absorption of TiO2 coated glass were investigated by UV-vis spectrophotometer. The results reveal that TiO2 in the film is still anatase phase after heat treatment at 350℃ and 500℃. With the annealing temperatures increasing from 20℃ to 500℃, the average crystal size increases just from 21.4 nm to 23.9nm, UV absorption of TiO2 coated glass increases from 2.2 to 2.7, visible light transmittance is high to about 80%.
