Nanorod tin oxide film was fabricated using nano aerosol spray pyrolysis deposition (SPD) on aluminosilicate glass. This method is very facile because the film is deposited at relatively low temperatures and at atmospheric pressures. Also, this method enables an easy in-line continuous mass production at a very low costs. Owing to the nano-porous characteristics of the nano-rod film, this type of film can be applied as an optical property modulation layers for OLED and thin film solar cell substrate. In this study, we have examined the formation mechanism of nanorod tin oxide and nanorod fluorine doped tin oxides. The nanorod was formed between the temperatures 500 ~ 600oC when the chamber atmosphere was well maintained using controlled atmospheric gas. The nanorod was formed by self-catalyzed tip growth mechanism. The tip of the nanorod was changed its shape when they were annealed under air atmosphere. This shape change does mean that the equilibrium surface the tip have been changed during air-annealing, which implies that the crystalline nature of the tip was not the same of the nanorod column. Also, we have investigated the optical properties of the nano-rod films deposited using nano-aerosol spray pyrolysis deposition methods. When the nano-rod film thickness was controlled well below several hundred nanometers they showed an increased visible light transmission as compared to the uncoated glass substrates, which encourages us to apply these nanorod films as an optical modulation layers of OLED lightings and photovoltaic cells.
