- 1. J. Phys. Chem. Solids 67, 789 (2006) , “Spectroscopic and magnetic studies of manganese ions in ZnO–Sb2O3–B2O3 glass system”, M. Srinivasa Reddy, G. Murali Krishna , N. VeeraiahZnO–Sb2O3–B2O3 glasses containing different concentrations of MnO ranging from 0 to 1.0 mol% were prepared. A number of studies, viz. optical absorption, infrared and ESR spectra and magnetic susceptibility, were carried out as a function of manganese ion concentration. The analysis of... (Read more)
- 2. Phys. Rev. B 74, 165203 (2006) , “Isotopic-mass dependence of the A, B, and C excitonic band gaps in ZnO at low temperatures”, S. Tsoi, X. Lu, A. K. Ramdas, H. Alawadhi, M. Grimsditch, M. Cardona, and R. LauckLow temperature wavelength-modulated reflectivity measurements of isotopically engineered ZnO samples have yielded the dependence of their A, B, and C excitonic band gaps on the isotopic masses of Zn and O. The observed dependence is analyzed in terms of the band gap renormalization by zero-point... (Read more)
- 3. Phys. Rev. B 73, 235209 (2006) , “Temperature dependence of the vibrational spectrum of a Li-OH complex in ZnO: Infrared absorption experiments and theory”, Kevin R. Martin, Philip Blaney, Gang Shi, Michael Stavola, and W. Beall FowlerConsiderable interest has developed in the potential use of IIVI oxides as electronic and optical materials. In several cases, alkali atoms have been suggested as dopants. We report on the theoretical and experimental investigation of infrared and vibrational properties of a Li-OH complex in... (Read more)

Garces, Ming Luo, Chunchuan Xu, Lihai Bai, L. A. BoatnerZinc oxide crystals grown by the seeded chemical vapor transport method have been annealed in zinc vapor at 1100 °C for 30 min. These thermochemical reduction treatments produce a deep red coloration in the crystals and increase their n-type electrical conductivity. Electron paramagnetic... (Read more)

Raghavaiah, B. Appa Rao , N. VeeraiahDifferential scanning calorimetric studies, spectroscopic studies (viz., optical absorption, ESR, infrared spectra) and thermoluminescence studies of ZnF2–MO–TeO2 (MO=ZnO, CdO and PbO) glasses doped with different concentrations of chromium ions have been investigated. Results have... (Read more)

Kakazey, M. V. Karpec, T. V. Tomila , M. M. RisticFreeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to nanosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum by sublimation of the solvent and salt decomposition to oxide by thermal... (Read more)
- 7. Appl. Phys. Lett. 81, 622 (2002) , “Role of copper in the green luminescence from ZnO crystals”, N. Y. Garces, L. Wang, L. Bai, N. C. Giles, L. E. Halliburton, G. CantwellElectron paramagnetic resonance (EPR), photoluminescence, and infrared optical absorption have been used to investigate a ZnO crystal before and after a thermal anneal for 1 h in air at 900 °C. The sample was an undoped high quality crystal grown by the chemical vapor transport method. In... (Read more)
- 8. J. Phys. Chem. Solids 63, 555-559 (2002) , “OH− impurities in co-doped LiNbO3:Cr 3+:ZnO congruent crystals”, G. A. Torchia, J. O. Tocho , F. JaqueInfrared optical absorption has been used to study OH−impurities into congruent co-doped LiNbO3:Cr3+:ZnO crystals doped with different Zn2+ concentration. The OH− IR absorption spectra present three bands that can be associated with different OH− complex centres available in the... (Read more)
- 9. Appl. Surf. Sci. 180, 308-314 (2001) , “The surface properties and photocatalytic activities of ZnO ultrafine particles”, Liqiang Jing, Zili Xu, Xiaojun Sun, Jing Shang and Weimin CaiWe prepared ZnO ultrafine particles (UFPs) by thermal decomposition of the precursor zinc carbonate hydroxide. The surface properties of the as-prepared particles were studied using TEM, XRD, BET, SPS, EPR, IR, and XPS. The surface contains active species such as oxygen deficiencies and hydroxyl...

- 10. Solid State Commun. 9, 2251-2253 (1971) , “Far infrared absorption in ZnO*1”, S. Perkowitz, R. K. Murty-Gutta , A. K. GarrisonFar infrared absorption measurements on as-grown and Li-doped ZnO have been made in the range 15-200 cm−1. A large Drude-type free-carrier absorption was observed, as were absorption bands near 115 and 160 cm−1. Combined absorption and EPR data on the Li-doped sample were interpreted... (Read more)
