“…In contrast, the absorption spectra of ZnS changed as it doped with Co, Mn, or Fe because of light scattered by grain boundaries, ions clusters, and defect states caused by different ion sizes. 30 Similar characteristics were reported in Mn-doped ZnS formed by co-precipitation procedure 31 and annealed ZnS/Mn formed using hydrothermal method, 18 where the absorption decreased with Mn doping. However, Patel et al 32 and Horoz et al 33 revealed that the optical absorption of ZnS increased as it doped with 10% Co or Fe.…”

Nano ZnS doped with Co, Mn, or Fe have been synthesized via thermolysis technique at different annealing temperatures (300, 400, and 500°C). The effect of doping and annealing temperature on the lattice parameter and crystalline size of ZnS are studied in detail by Rietveld refinement method of X‐ray diffraction data. To confirm the formation of a zinc blend structure of annealed and doped ZnS, Fourier‐transform infrared are investigated. The energy gaps of doped and annealed ZnS are determined using ultraviolet spectroscopy technique. Undoped and doped ZnS with Fe emitted violet, blue, and green colors depend on the annealing temperature. Moreover, Mn‐doped ZnS exhibits blue‐green emission, while Co‐doped ZnS has a blue emission only.
