Fabrication and photoluminescence of zinc silicate/silica modulated ZnO nanowires

Zinc silicate/silica modulated ZnO nanowires have been successfully prepared by a chemical vapour deposition route. The nanowires have a uniform diameter of -30 nm and length of 1 mm. Photoluminescence spectra show four peaks at 382, 398, 478 and 520 nm. Two new additional peaks at 398 and 478 nm ar...

Description
Summary:Zinc silicate/silica modulated ZnO nanowires have been successfully prepared by a chemical vapour deposition route. The nanowires have a uniform diameter of -30 nm and length of 1 mm. Photoluminescence spectra show four peaks at 382, 398, 478 and 520 nm. Two new additional peaks at 398 and 478 nm are assigned to modulation between ZnO and Si02. The formation mechanism of the surface modified ZnO-based nanowires is also proposed.
