The regularities of formation by the method of low-temperature crystallization from a solution of isolated CdSe, ZnSe nanoparticles with an average size of 4 nm were investigated. To prevent agglomeration of ZnSe, CdSe nanoparticles, a complex of techniques, such as stabilization of nanoparticles during synthesis, has been developed using thioglycerol as a stabilizer. The effect of stabilizer concentration on the properties of the obtained colloidal solutions of CdSe nanoparticles was investigated. Process parameters have been established and optimized to obtain stable colloidal solutions of CdSe, ZnSe quantum dots with different concentrations. The size and morphology of the synthesized nanoparticles were studied by electron microscopy. The optical properties of the obtained colloidal solutions of the quantum dots CdSe, ZnSe were investigated. The spin-coating method on modified quartz substrates produced film samples with different concentrations of CdSe, ZnSe nanoparticles and a packing density of <1 μm.
