Crystal Structure Determination of Low-Dimensional ZnS Powders Using EPR of Mn2+ Ions

Structures of low-dimensional ZnS powders doped with Cu, Co, and Mn were studied using Mn2+ ions as a paramagnetic probe. Particle sizes were 5–7 μm for ZnS:Cu, 7–10 μm for ZnS:Co, and 50–200 nm for ZnS:Mn. SpinHamiltonian parameters describing electron paramagnetic resonance spectra were obtained. Analysis of the spectra revealed that ZnS:Cu powder has cubic structure, ZnS:Mn powder has hexagonal structure with orthorhombic distortion, whereas ZnS:Co powder is a mixture of cubic and hexagonal phases in a 1:10 ratio.
