Iron doped zinc sulfide nanocrystals were obtained by colloidal synthesis using gelatin, lactose or polyvinyl alcohol as a stabilizing matrix. The structure of the nanocrystals was determined using X-ray diffraction (XRD). The influence of the concentration effect on the size and properties of ZnS nanocrystals, the optical absorption spectra and photoluminescence spectra were studied, and the types of optical transitions in these nanocrystals were determined.
