摘要
Ultrastable g-C3N4 assemblies consisting of amorphous/crystalline nanosheets with high quantum yields up to 78% were prepared for the first time. A reversible photoluminescence was observed from green to blue when the pH was adjusted. Conversely, this phenomenon was not observed for amorphous or crystalline samples. These assemblies exhibit high stability in PL devices.
