ZnO nanorods were prepared on the silicon (100) substrates using the chemical solution deposition method (CBD) without catalyst under a low temperature (90Β°C). The cool water was used to dissolve the mixture of zinc nitrate hexahydrate (Zn (NO 3 ) 2 β’6H 2 O) and methenamine (C 6 H 12 N 4 ) in order

Abstract
Tubular ZnO nanostructures have been obtained via a hydrothermal method at low temperature (90 Β°C) without any catalysts or templates. The XRD measurement reveals that the tubes are single crystals with hexagonal wurtzite structure. SEM shows that the diameters of ZnO nanotubes ranged from 400 to 550 nm. The Raman and PL spectra indicate that oxygen vacancies or Zn interstitials are responsible for the green emission in the ZnO nanotubes. A possible growth mechanism on the formation of crystalline ZnO nanotubes has been presented. (Β© 2010 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
