- 1. Jpn. J. Appl. Phys. 38, L113 (1999) , “Yellow Emission from Zinc Oxide giving an Electron Spin Resonance Signal at g=1.96”, Naoki Ohashi, Tomokazu Nakata, Takashi Sekiguchi, Hideo Hosono, Masafumi Mizuguchi, Takaaki Tsurumi, Junzo Tanaka, Hajime HanedaZnO polycrystals doped with Li, Cu or Al were prepared by solid-state reactions and their cathodoluminescence (CL) and electron spin resonance (ESR) spectra were measured. A strong yellow emission centered at 2.0 eV was observed for the Al-doped specimen and its intensity was higher than that of... (Read more)
- 2. Solid State Commun. 25, 77-80 (1978) , “Exchange broadened, optically detected ESR spectra for luminescent donor-acceptor pairs in Li doped ZnO”, R. T. Cox, D. Block, A. Hervé, R. Picard and C. SantierR. HelbigApplication of optically detected ESR to the yellow photoluminescence of Li doped ZnO gives ESR spectra for shallow donor - lithium acceptor pairs, showing that at least a fraction of the yellow emission is donor-acceptor (D-A) luminescence. The distribution of separations rDA gives a spectrum of... (Read more)
- 3. J. Lumin. 5, 385-405 (1972) , “Trapping and recombination processes in the thermoluminescence of Li-doped ZnO single crystals*1”, D. ZwingelThe thermoluminescence of Li-doped ZnO single crystals is investigated in the temperature range 4.2–300 K. A glow curve is observed with three maxima, two of them emitting the strong polarized yellow luminescence of ZnO. By varying the Li concentration in the range 0.1–200 ppm a change... (Read more)
- 4. J. Phys. Chem. Solids 32, 499-509 (1971) , “Trapped-hole centers containing lithium in MgO, CaO and SrO”, O. F. SchirmerWe report an ESR investigation of a center in MgO, CaO and SrO consisting of an O− ion neighbored by a substitutional Li+ ion. The center is identified by comparison with the isomorphous centers in ZnO and BeO and with the analogous V1, VOH and VF centers in the alkaline earth oxides. The... (Read more)
- 5. 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)
