The photoluminescence (PL) emission mechanism of graphitic carbon nitride (g-C3N4) is still ambiguous and the application of PL g-C3N4 powder as a solid sensing platform has not been explored. Herein we highlight a strategy to prepare g-C3N4 powder with strong green PL by doping phenyl groups in a carbon nitride network. Compared with pristine g-C3N4, doping of phenyl groups greatly enhances the PL efficiency and Stokes shift. Theoretical calculations based on density function theory indicate that phenyl groups change the electronic structure of the carbon nitride network and have an obvious contribution to the LUMO of phenyl-doped g-C3N4, which may be the main reason for the enhancement of the PL efficiency and Stokes shift. Taking advantage of the high PL efficiency, large Stokes shift and high photostability, phenyl- doped g-C3N4 powder shows promising application for the imaging of latent fingerprints.
