报告简介:

Carbon dots (CDs) – small crystalline or amorphous carbon-based quasi-spherical nanoparticles – have recently attracted much attention as promising fluorescent materials. One of their widely accepted advantages is the simplicity of the formation of highly luminescent CDs from a wide variety of organic precursors. At the same time, several recent studies on these chemically synthesized CDs raised questions about the chemical nature of the resulting products; their strong luminescence can originate from the presence of molecular organic fluorophores. On the other hand, use of proper synthetic procedures yield purely carbon dot samples of different sizes; color-tunable fluorescence of CDs with blue, green, yellow, orange, red and even near-infrared emission can be achieved, with the color depending on size of the π-conjugated domains in the CD graphitic core. Recently, we have extended the family of these light-emitting colloidal carbon nanoparticles towards other shapes, such as nanorods with linearly polarized emission, nanobelts andnanorolls. Application of CDs in luminescent solar concentrators has been demonstrated.
