Obtaining and properties of the system «nanoparticle carbon material – CdS quantum dots»
Abstract
Quantum dots (QDs) today are the objects of intense research of many scientific groups. QDs semiconductor compounds A2B6 attract special attention due to the ability to control the size of QDs in the process of their synthesis, which gives the opportunity to obtain the necessary electronic and optical properties. Successful solution to the problem of obtaining QDs semiconductor materials with appropriate controllable properties largely depends on the choice of environment in which their synthesis is realized. Encapsulation of nanoparticles or introducing them into a chemically inert matrix makes it possible not only to isolate QDs from a chemically active medium, but also to obtain a system of nanoparticles with certain given sizes (pore size matrices). For this reason, the promising material of the matrix is a nanoporous carbon material (NCM) that is chemically inert to most alkalis and acids, and in which it is possible to obtain the required pore sizes for the introduction of QDs.
