Within the framework of the modified Lifshitz-Slyozov-Wagner theory, we study the mechanisms and kinetics of formation of ZnO nanocrystals from oversaturated solution accounting the dependence of optoelectronic properties of semiconductor on crystal size. It is shown that the size distribution function can be described by the generalized Lifshitz- Slyozov-Wagner function corresponding to growing ZnO nanocrystals governed in parallel by two mechanisms, viz. the diffusion and the Wagner’s ones. Comparison of experimentally obtained data with theoretically computed ones represented as the size distribution functions and the temporal dependences of the mean sizes of ZnO nanocrystals enables to estimate the constants of the rate of growth of them at the stage of the Ostwald’s ripening. We also propose the way for estimating the magnitude of the specific surface energy at the nanocrystal-liquid interface.
