Abstract

The invention discloses a preparation method of transparent conducting film glass and belongs to the technical field of glass preparation. According to the preparation method, polyvinylpyrrolidone powder is dissolved into a complexed stannous sulfate solution; metal ions in transparent homogenized sol can have very good stability by utilizing low surface energy of polyvinylpyrrolidone, so that thelight transmittance of the transparent conducting film glass is improved; a main component in the transparent homogenized sol is zinc oxide and a doping component is aluminum nitrate nonahydrate; thegrowth of zinc oxide crystal grains is inhibited so that an impurity scattering center formed in a thin film is reduced and the visible light transmittance of the thin film is increased; the contentof current carriers is increased along the rising of an aluminum ion doping concentration and the resistivity is reduced; the crystal grain fineness of the zinc oxide and tin oxide is relatively smalland the compactness between the zinc oxide and the tin oxide is improved; the crystal interface scattering of the current carriers is reduced and the mobility of the current carriers is improved, sothat the resistivity of the transparent conducting film glass is reduced and the conducting performance is improved; the transparent conducting film glass has a wide application prospect.
