- 1. J. Phys. Chem. Solids 55, 1353-1356 (1994) , “EPR of [FA]0 centres in zinc chalcogenides”, K. Tarkpea, A. Ots , V. Nikitenko[FA]0 centres in ZnO and ZnS single crystals have been detected by electron paramagnetic resonance. The [FA]0 centre consists of an anion vacancy with a localized electron and a monovalent substitutional impurity replacing an adjacent Zn2+ ion. This impurity is probably a Li+ ion in the case of ZnO... (Read more)
- 2. J. Non-Cryst. Solids 58, 165-178 (1983) , “Electron paramagnetic resonance of Cu2+ and V4+ ions in borate glasses”, L. D. Bogomolova , V. A. JachkinThe EPR spectra of Cu2+ and V4+ ions have been studied in binary RO---B2O3 glasses (where R = Ba, Sr, Pb and Zn) and in ternary PbO---ZnO---B2O3 glasses. The main results of an EPR study of alkali-borate glasses are briefly reviewed. Three distinct EPR spectra of Cu2+ ions in barium-borate glasses... (Read more)
- 3. J. Non-Cryst. Solids 34, 339-356 (1979) , “ESR and optical absorption of cupric ion in borate glasses”, H. Hosono, H. Kawazoe and T. KanazawaESR and optical absorption of Cu2+ were measured in xNa2O(100−x)B2O3 (1 ≤ x ≤ 75), x ZnO(100−x)B2O3 (46 ≤ x ≤ 64) and x Pb(100−x)b2O3 (20 ≤ x ≤ 75) glasses, where x is expressed in mol.%. Spin hamiltonian parameters and ligand field... (Read more)
- 4. Thermochim. Acta 29, 247-252 (1979) , “Combined EPR and TG techniques : comparison of the thermal reduction of chromium (VI) ions in some zinc chromates and chromate-oxalate mixtures*1”, Z. Gabelica , E. G. DerouaneR. HubinLower oxydation state chromium species which are successively formed and stabilized upon thermal reduction of chromate (VI) ions, are studied by combined EPR and TG-techniques.The spontaneous oxygen release occuring during the vacuum thermal treatment of some zinc chromates leads to the formation of...

- 5. Advances in Molecular Relaxation Processes 5, 211-218 (1973) , “Chemisorption of oxygen on transition metal oxides studied by EPR”, Krystyna DyrekThe method was applied to the investigation of adsorption of oxygen on the transition metal oxides MnO, FeO, CoO, Cu2O, and their solid solutions in the diamagnetic matrices ZnO and MgO. It has been found that in the case of pure oxides and their solid solutions at high magnetic metal ion... (Read more)
- 6. J. Lumin. 6, 376-384 (1973) , “2S1/2 state ions in inorganic luminescent materials*1”, G. Born, A. Hofstaetter , A. ScharmannSelected examples of impurity ions with one unpaired electron in an unfilled shell are Pb3+ ions in II–IV compounds (ZnO, ZnSe, ZnTe), Pb3+ in CaWO4,F centres in alkali halides and Ag0 and Au0 atoms in radiophotoluminescent (RPL) glasses. Comparative studies of EPR, luminescence,... (Read more)
- 7. J. Phys. Chem. Solids 29, 1407-1429 (1968) , “The structure of the paramagnetic lithium center in zinc oxide and beryllium oxide”, O. F. SchirmerIf ZnO and BeO crystals containing Li are irradiated with u.v. or X-rays, a paramagnetic defect center is created consisting of a hole captured at an O2− ion next to a substitutional Li+ impurity. Because of the polarity of the crystals, the hole assumes its lowest energy, if the... (Read more)
