dc.description.abstractEnX-band electron spin resonance (ESR) spectra and fluorescence measurements were performed on Mn-doped Na<sub>2</sub>ZnP<sub>2</sub>O<sub>7</sub> (NZPO) single crystal synthesized by the Czochralski pulling method and glasses synthesized by the quenching process. For the single crystal, ESR angular dependences were measured in both the zx and xy plans of the NZPO lattice. The fine and hyperfine structure parameters and <i>g</i>-factor values were determined by modelling the experimental spectra. Using the Newman superposition model, the resonating centres in the single crystal and powder (crushed from crystals) samples are assigned to Mn<sup>2+</sup> ions substituting for both zinc and sodium. For the glass sample the analysis of the ESR data shows that Mn<sup>2+</sup> ions substitute for the Na<sup>+</sup> ions. These interpretations are confirmed by the fluorescence measurements with a unique broad red band for the glassy compound and the presence of two emission bands (green and red) in the case of the crystal sample.
