Abstract

ZnO well-faceted microfibers with periodic junctions were prepared by an evaporation and deposition process. A study on the photoluminescence (PL) and PL microscopy fibers showed that it could serve as microscale waveguides and emit enhanced green lights at the junctions under UV excitation.

Abstract

ZnO nanostructures, including nanotowers, nanovolcanoes, nanorods, nanotubes, and nanoflowers is grown by using the hydrothermal technique. Most of the ZnO nanostructures reveal the perfect hexagonal cross section and well-faceted top and side surfaces.

Abstract

Well-aligned ZnO nanorod and nanobolt arrays were synthesized on p-type Si(100) substrates by a simple physical vapor deposition method. During the growth process when the carrier gas was switched from Ar to air, the nanorods changed into nanobolts completely. The mechanism for this transformation process is discussed. The room-temperature photoluminescence spectrum of nanobolts showed a strong ultraviolet emission at 3.26 eV coupled with a weak deep level energy emission at 2.48 eV. The origin of the ultraviolet emission of nanobolts was investigated by temperature-dependent photoluminescence spectra. [ABSTRACT FROM AUTHOR]
