We investigated the thickness effect on the photophysics and charge carrier kinetics of graphitic carbon nitride nanoflakes (g-CNN) by using ultraviolet visible diffuse reflectance spectroscopy, atomic force microscopy, femtosecond transient absorption spectroscopy, and picosecond time-correlated single photon counting measurement. For the first time, we found that g-CNN displays a layer-dependent indirect bandgap and layer-dependent charge carrier kinetics.
