To prevent the agglomeration of ZnSe nanoparticles, a set of techniques has been developed, such as stabilization of nanoparticles in the synthesis process using 1-thioglycerol and thioglycolic acid as a stabilizer. It is shown that the concentration of thioglycerol is 2.5 mmol, which allows to obtain stable colloidal solutions of ZnSe quantum dots with an average size of ~ 3.0 ± 0.15 nm. The spin-coating method on modified quartz substrates obtained samples of densely packed films of ZnSe nanoparticles stabilized with 1-thioglycerol and thioglycolic acid, the film thickness is ~ 430 nm. The morphology, composition and structure of the obtained films were studied by scanning electron microscopy. The optical properties of the obtained colloidal solutions of ZnSe quantum dots and films based on them have been studied Product Description popup.authors Matvieievska Nionila A Shulichenko Olena M popup.nrat_date 2021-03-17 Close
