Abstract:

LiNO3-doped TiO2 thin films on glass-ceramics were prepared by sol-gel dip coating. The influence of LiNO3 addition on the phase transformation temperature was studied. The transformation temperatures of non-crystalline to anatase and anatase to rutile are originally 520°C and 880°C without the addition of LiNO3. By adding 5%LiNO3 the two transformation temperatures decrease to 440°C and 580°C, respectively. The average size of the particles was found to be around 40nm for the LiNO3- doped TiO2 film annealed at 600°C.
