文摘
- •
Relationships between structural and optical properties in g-C3N4 are proposed.
- •
XRD, Raman, steady and time resolved luminescence, PLE, and reflectivity are reported.
- •
Melem presents the main optical features at higher energies with respect to PCN.
- •
A sub-nanosecond decay time is assigned to the recombination from the σ* bands.
- •
A slower decay time is assigned to recombinations within the single triazine units.
