Indigo Carmine Dye

The photocatalytic degradation of indigo carmine dye was studied using tungsten doped BiVO4. Bismuth vanadate powder has been synthesized by sol-gel technique. The incorporation of W ions into BiVO4 was confirmed by EDX. The photocatalytic activity was studied using different samples of BiVO4 by variation of pH, concentration of dye, dose of semiconductor and light intensity. It has been found that degradation of dye is more effective in presence of W doped BiVO4, It shows the role of tungsten ions for enhancing degradation of indigo carmine by reducing the recombination of photogenerated electrons and holes.

Sol Gel Process

Based on TEOS system and sol-gel process, together with catalysts, Antireflective coating films prepared by sol—gel on glass substrate have been processed by rapid thermal annealing (RTA). the refractive index and thinkness of SiO2 film is exactly controlled. The films are characterized by ellipsometer and SEM respectively. The quantum states in these processions are found and discussed.

Coating Technique

Sol-gel thin films prepared by dipping coating technique, sol–gel derived bulk were prepared from constant water (H2O)/tetraethyl-orthosilicate (TEOS) ratio, dipping coating were carried out at different dipping speed 100mm/min, 200mm/min, 300mm/min, 400mm/min, 500mm/min respectively. The films are characterized by ellipsometer and SEM respectively. The experimental results show the thickness of films are become bigger and bigger with the dipping speed increasing.The refractive index change is not obvious.
