ZnO:Mn nanoparticles (of 3–5 nm) immobilized in polyethylene matrix are synthesized. The samples with different content of the manganese (5%, 10%, and 20% of initial solution of Mn and Zn precursors) are investigated by means of ESR, PL, and XRD. Thus, the behaviour of the Mn impurities in ZnO is studied. As revealed, the most of the manganese in ZnO forms the second un-determined phase MnOx or substitute zinc in cation sublattice at the surface layer of the nanoparticles. The value of con-stant of hyperfine structure of Mn is higher than an expected one (|A|???89.5?10?4 cm?1 that is significantly differ from the constant of hyperfine structure of Mn incorporated into ZnO single crystal (76?10?4 cm?1)). Photoluminescence measurements reveal wide band of emission in green–red region (500–600 nm), with different position of the maximum depending on the manga-nese content.
