Abstract

Nanocrystalline zinc oxide powder has been successfully prepared by addition of NaOH and urea as the base source via the microwave, resistance heating and conventional hydrothermal process at temperature < 100oC. The effects of synthesis conditions and chemical additives on the particulate properties such as the particle morphology and grain size discussed. The morphology and grain size was monitored by SEM, XRD and BET analysis. Zinc oxide nanopowders was obtained by the decomposition of different zinc saltz in a aqueous solution under alkaline conditions or with addition of urea. The properties of zinc oxide as scintillating material were tested as a function of the technology of production and grain size. The luminescence of zinc oxide nanopowders was studied under three kinds of excitation: pulsed electron beam, nitrogen laser and continuous x-ray excitation.
