- 1. Superlatt. Microstruct. 39, 247-256 (2006) , “Optical and morphological features of bulk and homoepitaxial ZnO”, R. Yakimova, G.R. Yazdi, N.T. Son, I. Ivanov, M. Syväjärvi, S. Sun, G. Tompa, A. Kuznetsov , B. SvenssonZnO substrate crystals from two different sources, and epitaxial layers have been studied by SEM, AFM, photoluminescence and EPR. Although fabricated by the same growth principle, i.e. the hydrothermal technique, the substrates differ in terms of purity and structural quality. In the PL spectra of... (Read more)
- 2. Mater. Sci. Eng. C 25, 614-617 (2005) , “Incorporation of cobalt into ZnO nanoclusters”, Igor Ozerov, Françoise Chabre and Wladimir MarineThe structural, optical and magnetic properties of nanostructured ZnO films co-doped with cobalt and aluminium have been studied. The nanocrystalline films, with cluster sizes in range 50–100 nm, were deposited by pulsed laser ablation in a mixed atmosphere of oxygen and helium. The... (Read more)
- 3. Appl. Phys. Lett. 85, 1601 (2004) , “Different origins of visible luminescence in ZnO nanostructures fabricated by the chemical and evaporation methods”, D. Li, Y. H. Leung, A. B. Djurisic, Z. T. Liu, M. H. Xie, S. L. Shi, S. J. Xu, W. K. ChanWe prepared ZnO nanostructures using chemical and thermal evaporation methods. The properties of the fabricated nanostructures were studied using scanning electron microscopy, x-ray diffraction, photoluminescence, and electron paramagnetic resonance (EPR) spectroscopy. It was found that the... (Read more)
- 4. Appl. Phys. Lett. 84, 2635 (2004) , “Visible photoluminescence in ZnO tetrapod and multipod structures”, Aleksandra B. Djurisic, Yu Hang Leung, Wallace C. H. Choy, Kok Wai Cheah, Wai Kin ChanThe properties of ZnO tetrapod and multipod structures were investigated using scanning electron microscopy, x-ray diffraction, photoluminescence (PL), and electron paramagnetic resonance (EPR) spectroscopy. While there is relationship between g = 1.96 EPR and green PL in some of the samples,... (Read more)
- 5. Mater. Sci. Eng. A 375-377, 620-624 (2004) , “Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method”, Z. V. Marinkovic, O. Milosevic, M. V. Nikolic, M. G. 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)
- 6. J. Phys. Chem. Solids 64, 1027-1035 (2003) , “Optical absorption and fluorescence properties of Er3+ ion in MO–WO3–P2O5 glasses”, P. Subbalakshmi , N. VeeraiahTungsten phosphate glasses mixed with the three different modifier oxides, viz. PbO, ZnO and CaO doped with Er2O3 were prepared. The glasses were characterised by X-ray diffraction spectra, electron microscopy and differential thermal analysis. Optical absorption and photoluminescence spectra of... (Read more)
- 7. J. Appl. Phys. 79, 7983-7990 (1996) , “Mechanisms behind green photoluminescence in ZnO phosphor powders”, K. Vanheusden, W. L. Warren, C. H. Seager, D. R. Tallant, J. A. Voigt, B. E. GnadeWe explore the interrelationships between the green 510 nm emission, the free-carrier concentration, and the paramagnetic oxygen-vacancy density in commercial ZnO phosphors by combining photoluminescence, optical-absorption, and electron-paramagnetic-resonance spectroscopies. We find that the green... (Read more)
- 8. Appl. Phys. Lett. 58, 1742 (1991) , “Electron spin resonance study of laser-annealed (Zn,Mn)O ceramics”, Katsuyasu Kawano, Ryouhei Nakata, and Minoru SumitaInvestigations have been made on the effects of pulse laser annealing on the ceramics (Zn,Mn)O by means of electron spin resonance (ESR) measurements. A remarkable change in the ESR spectrum was observed after annealing by a Nd:YAG pulse laser (=1.064 µm, 57 J/cm2). It... (Read more)
