Abstract
Carbon nanostructures are attracting increasing interest because of their unique and novel properties. This paper reports a simple method for the synthesis of highly uniform fluorescent carbon nanoparticles (CNPs). The morphology and structure of the resulting CNPs were characterized by transmission electron microscopy, and the room-temperature optical properties of the CNPs were examined by photoluminescence spectroscopy. The particle size of the synthesized CNPs could be controlled easily by varying the reaction time and precursor concentration. The prepared samples had high colloidal stability and strong excitation-independent fluorescent properties, which can be used in biochemical and solid-state lighting applications.
