Graphitic carbon nitride (g-C₃N₄) is energetically investigaged for application to white LEDs, photodiodes, and photocatalyst materials because it has a bandgap of about 2.7 eV and consisits of only two low environmental impact atoms, carbon and nitrojen. However, it is very difficult to preparate fine thin films using g-C₃N₄. In this study, we present the preparation method of fine g-C₃N₄ thin films by electrostatic spray deposition method using nano-amrphous g-C₃N₄ dispersed in dimethyl sulfoxide (DMSO) solution.
