Shake up satellites and fluorescence property of carbon nitride and hydrogenated carbon nitride: Annealing effect

► Composition of Carbon nitride (CNx) & Hydrogenated carbon nitride (HCNx). ► Shake up satellites peak in XPS of a-HCNx. ► Shake up peaks remove at high annealing temperature. ► No shake up peak in CNx film. ► Fluorescence effect in Raman spectra of a-HCNx and CNx film.
