The ZnS:Mn, Mg powder is fabricated by self-propagating high-temperature synthesis with the simultaneous introduction of Mn and Mg impurities. It is found that the simultaneous introduction of Mn and Mg impurities leads to the nonuniform distribution

We have studied the EPR of Mn2+ ions in three samples of cubic nano-ZnS made by different technologies and having different nanoparticle sizes. Manganese occurs in the samples as an uncontrolled impurity. The EPR spectra can be described by two compo

For the first time we studied Raman, exciton and EPR spectra of PbI2 layered crystals of 2H polytype doped with high concentration of Mn impurity. A novel type of Fermi resonance was found. The anomalous temperature shift of the exciton band n = 1 wa

Nanocrystalline silicon films formed using laser ablation of silicon targets were studied using electron spin resonance. The measurements were performed in the X band with modulation of the magnetic field at a frequency of ∼100 kHz at temperatures

ENDOR spectra and ENDOR-induced EPR spectra (dependences of ENDOR signals vs. the value of magnetic field B) of γ-irradiated bone plates and powders are studied. Typical ENDOR spectrum consisted of two signals centred at the Larmor frequencies of 1H

After fast neutron irradiation with a dose of 10 19 cm −2 a new defect, labeled Ky5, has been revealed in the EPR spectra in addition to the dominant spectrum of the negatively charged silicon vacancy, the T1 center. Angular variation of the Ky5 sp
