Montenegro, D. N. Hortelano Santos, Vanesa Martínez Sacristán, Óscar Martínez Tomas, M. C Sallet, V. Muñoz Sanjosé, V. Jiménez López, Juan Ignacio 2013 Producción Científica A detailed optical characterization by means of micro Raman and cathodoluminescence spectroscopy of catalyst-free ZnO nanorods grown by atmospheric-metal organic chemical vapour deposition has been carried out. This characterization has allowed correlating the growth conditions, in particular the precursors partial-pressures and growth time, with the optical properties of nanorods. It has been shown that a high Zn supersaturation can favor the incorporation of nonradiative recombination centers, which can tentatively be associated with ZnI-related defects. Characterization of individual nanorods has evidenced that ZnI-related defects have a tendency to accumulate in the tip part of the nanorods, which present dark cathodoluminescence contrast with respect to the nanorods bottom. The effect of a ZnO buffer layer on the properties of the nanorods has been also investigated, showing that the buffer layer improves the luminescence efficiency of the ZnO nanorods, revealing a significant reduction of the concentration of nonradiative recombination centers. application/pdf http://uvadoc.uva.es/handle/10324/32428 eng AIP Publishing Espectroscopia Raman Raman Spectroscopy Influence of metal organic chemical vapour deposition growth conditions on vibrational and luminescent properties of ZnO nanorods info:eu-repo/semantics/article TEXT UVaDOC.
