Investigation of the optical properties of the g-C3N4 thin film synthesized from melamine organic mass

Abstract

In this paper, the effect of the mass of the melamine precursor during the synthesis of a thin film of g-C3N4 on glass and silicon substrates was investigated using the method of pyrolytic decomposition of melamine with subsequent thermal polymerization. Optical measurements such as photoluminescence spectra, absorption spectra and transmission spectra were carried out in the article. The energy levels in the recombination process were detected by the Gauss analysis method and it was found that the decrease in energy peaks with an increase in the mass of melamine. And they also see a reduced absorption and an increased ability to penetrate in the wavelength range of 450-800 nm with an increase in the mass of melamine.
