Optical properties of fluorine-doped SnO2 films

Abstract
Thin layers of conducting glass (SnO2: F) 3‐Ω/⧠ sheet resistance were chemically deposited on borosilicate glass slides. Conducting glass showed high transparency around solar maxima (0.5 μm) and low reflectivity compared with silicon. In an optical investigation of the conducting glass at room temperature a direct allowed transition at 4.13 eV and an indirect allowed transition at 2.69 eV together with an assisting phonon of 0.085 eV were observed.
