Synthesis of carbon quantum dots and study of optical properties

Operation co-funded by EU cohesion policy (European Social Fund (ESF)) under the programme EU Structural Funds Investments - LT - ERDF/ESF/CF/YEI (2014LT16MAOP001), managing authority: Finansų ministerija. The source names no beneficiary for this operation. Location: Vilnius County (NUTS LT011); Lithuania. Budget: total eligible expenditure EUR 2,816.33; EU co-financing EUR 2,816.33 (co-financing rate 100%), as stated by the source. Runs 2018-10-01 to 2019-04-30.

Summary from Kohesio (English machine translation by the source): Carbon quantum dots have unique physico-chemical properties (UV and visible radiation absorption and emission, biocompatibility, low toxicity, water solubility, chemical inertia, light surface modification, photostability, etc.), so they are intensively studied for possible applications in LEDs, biosensics, bioimagery medicine, and in the rapidly developing field of teranostics — monitoring of the distribution of medicines and their activity in the body. So far, the greatest challenge for scientists is the synthesis of uniform-sized (monodispersive) carbon quantum points, nanoparticle aggregation. There are also difficulties in the targeted modification of the carbon quantum dot surface depending on the application area. The size of the particles obtained has a strong influence on their physical properties, so control of this parameter is of particular importance and attention is paid to it. The properties of carbon quantum dots may also be altered by the addition of heteroatoms (e.g. nitrogen) by oxidation or by chemical modification of the surface. During the project, various synthesis methods (electrochemical oxidation, chemical oxidation, ultrasonic synthesis, microwave synthesis, thermal degradation, hydrothermal synthesis, etc.) will synthesise carbon quantum points and select the most optimal method(s) of synthesis. The various parameters of synthesis (duration, temperature, pH, solvent, oxidiser/reducer) will be further modified and their influence on the size, monodispersity and optical properties of the carbon quantum dots formed.
