Color‐tunable photoluminescence from continuous graphitic carbon nitride (g‐C3N4) thin films is demonstrated. The films are employed in light‐emitting diodes. A strong redshift of the electroluminescence with respect to photoluminescence is observed and a model for this uncommon behavior is provided.
