Influence of aging and annealing on the properties of silica films produced with sol-gel method

The paper presents the results of investigations involving the influence of aging and annealing of the sol films on the final parameters of the obtained silica films. Both technological process and measurement method were described. The changes of refractive index were presented as well as the changes of film thickness of sols deposited on glass substrates during their aging under ambient conditions. The influence of the annealing process of films on their final parameters was examined. Silica films on glass substrates were deposited using dip coating method.
