An iridescent carbon nitrogen movie g-C3N4 was shaped by chemical vapor deposition (CVD) on an aluminum sheet ranging from melamine cyanurate as a precursor at a temperature of 600 °C. The movie was simply indifferent and completely characterised utilizing numerous strategies, together with X-ray powder diffraction, UV − Vis and infrared spectroscopies, and discipline emission scanning microscopy. The fabric exhibited a specific layered microstructure consisting of stacks of nano-/micro-sized oak-leaf-shaped particles. The UV − Vis spectrum exhibited two outlined bands comparable to localized electrons; nonetheless, the obvious direct bandgap was 3.1 eV, much like that of bulk g-C3N4. The IR spectrum was much like that of bulk materials, with variations in band intensities of the bending zone of tri-s-triazine models, within the vary of 900 − 800 cm−1. The two D unfolding of the fabric with the formation of a skinny layer composed of oak-leave-like particles led to structural iridescent colours. Because of this, functions in optoelectronics and photovoltaic cells primarily based on skinny movies ready by the reported synthesis route could also be envisaged, benefiting from the properties of structural colours.
