In this paper, high transmission silica thin films have been prepared by dip-coating process from a new silicon-alkoxide solution. The prepared sol was stable for 45 days which is very important to characterize the coating process. The optical properties as a function of aging time, withdrawal rate, and heat treatment parameters (temperature and time) have been studied. %U https://ijcce.ac.ir/article_7627_8f69c7ece6f6daaaba1b620508cca094.pdf
