Production and investigation of layered zinc sulfide(selenide)/insulator nanocomposites

Layered ZnS/SiO$_{2}$, ZnS/Al$_{2}$O$_{3}$, and ZnSe/SiO$_{2}$ nanocomposites have been studied. It has been shown that the use of the Maxwell–Garnett and Bruggeman models, as well as the Luyengi formula, in the low dispersion region makes it possible to predict the production of films with a given effective refractive index. Calculated values of the refractive index correlate well with experimental data. The maximal discrepancy between the theoretical and experimental values of the refractive index and the maximal value of the depolarization factor depend on the structure and microstrains.
