Colloidal semiconductor quantum dots are our core product. They stand out on the market with their precisely defined and controlled surface and a high quality, modifiable surface. The resulting light emission is both spectrally narrow and efficient, which makes QNA.dots a nanomaterial of particular attraction for industry customers. With the use of our proprietary technology of continuous synthesis, we are able to meet growing demand for quantum dots.
QNA.dots are colloidal nanocrystals made of semiconductor materials.
They are characterised by a precisely defined size and its controlled distribution, as well as a high quality surface. All these properties guarantee a spectrally narrow and efficient emission of light. Depending on the applications required, the surface of QNA.dots may be subject to modification which, if carried out in accordance with QNA’s proprietary procedure, makes it possible to maintain the highest quality of quantum dots, including their high dispersibility in both organic and aqueous solvents without sticking.
