| description | Zinc oxide (zno) is applications in high efficiency electronic and optoelectronic devices. The present
study follows two objectives. First, synthesis of vertical and inclined well-aligned
zno nanorods (nrs) on a nylon substrate via the hydrothermal method, and
subsequently fabricate the highly flexible low-cost ultraviolet photodiodes (uv-pds)
and hydrogen (h2) gas sensor devices. Pre-heat treatment of zno seeds/substrate at
180°c with varying duration (0.5-6 h) shows important changes. Morphological
observations revealed the formation of aligned hexagonal-like shaped nanorods when
the diameter, length (aspect ratio), surface area and density increase with increasing
heat treatment time. The x-ray diffraction analysis confirms the formation of
wurtzite zno phase with a preferred orientation along (002) direction and enhanced
crystallinity. Photoluminescence spectra exhibited a strong and sharp ultraviolet
(uv) near band edge emission peak that was higher than that of the broad peak.
Temperature and duration to produce uniform zno seeds was 180°c for 3 h. |
