Optical properties of citric acid and ethylenediamine based carbon nanoparticles

摘要

In this article we report an effective hydrothermal synthesis of bright-emissive nanoparticles from citric acid andethylenediamine. Also, we demonstrate methods for separation of carbon nanoparticles such as high speedcentrifugation and size-exclusion liquid chromatography. These nanoparticles due to their high quantum yield canbe used as markers for biological tissues, liquids and cells.
