Hydrothermal aggregation induced crystallization: a facial route towards polycrystalline graphite quantum dots with blue photoluminescence

Author affiliations

Abstract

A facile one-step hydrothermal method with NH3 as a passivation agent was developed for the preparation of polycrystalline graphite quantum dots (GQDs). The prepared GQDs exhibited high crystallinity, a uniform size of 3.8 nm and blue photoluminescence at 402 nm. Moreover, a hydrothermal aggregation induced crystallization mechanism was proposed to explain the formation of the GQDs.
