Product Description


Carbon quantum dots (CQDs), also known as carbon dots (CDs), are a family of zero-dimensional carbon nanomaterials with exceptional fluorescence capabilities. They are composed of ultrafine, distributed quasi-spherical carbon nanoparticles with dimensions less than 10 nm. Compared with other heavy metal semiconductors, water-soluble CQDs are characterized by low toxicity, high hydrophilicity, high stability, and eco-friendliness. This enables their applications in biomedicine, optoelectronics, catalysis and sensing. Alfa Chemistry is committed to providing you with water-soluble CQDs with excellent properties. If you need, please feel free to contact us.
