摘要：
Nano ZnS doped with Co, Mn, or Fe have been synthesized via thermolysis technique at different annealing temperatures (300, 400, and 500 degrees 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.
