One of the most effective strategies for reducing the surface defects in nanocrystals is the shell growth on the already formed cores. This approach provides not only an increase in the photoluminescence quantum yield (PL QY) but also prevents the diffusion of cations and anions from the core material. Gram scale synthesis of the green-emitting core (10 g) was performed by interaction of highly reactive substituted selenourea ((Z) - N -(octadec-9-enyl)morpholine-4-carboseleno-amide) with the cadmium and zinc linoleates mixture at 240 °C. Verification of the shell growth method based on the volume ratios of the core and the core with a shell led to the creation of a series of core/shell/shell Cd0.1Zn0.9Se/CdxZn1-xS/ZnS(x=0.1;0.25;0.4;0.6;0.7...
