Nanoparticles ZnO:Mn (3–5nm) immobilized in polyethylene matrix were synthesized. The samples with different content of the manganese (5, 10 and 20%) in the initial solution of the Mn and Zn precursors were investigated by means of ESR, PL and XRD. Thus the behavior of the Mn impurities in ZnO was studied. It was observed that most of the manganese in ZnO form second undefined phase MnOx or substitute the zinc in cation sublattice at the surface layer of the nanoparticles. The mean value of constant of hyperfine structure of Mn is higher than expected one (<A> = (94±3)·10⁻⁴ cm⁻¹) that is significantly differ from the constant of hyperfine structure of Mn incorporated into single crystal ZnO (76·10⁻⁴ cm⁻¹). Photoluminescence measurements has revealed wide band of emission in green-red region 500–600 nm, with different position of the maximum depending on the manganese content.
