Abstract

In this paper, we have studied the optical properties of $TiO_2$ thin film by adding the additives of PEG, PEO and both of them. As a variable amount of additives was added into $TiO_2$, the transmittance of $TiO_2$ thin film was decreased. When the 20 wt% of additives mixed with PEG and PEO was added into $TiO_2$, the transmittance of $TiO_2$ thin film showed higher than that of 10 wt% of additives mixed with PEG and PEO. As a results, we could conclude that the additives makes pore in $TiO_2$ thin film and it improves the transmittance of $TiO_2$ thin film.
