Abstract

The field emission and photoluminescence characteristics of zincoxide nanowires were studied. The nanowires were synthesized by a metal catalyzed vapor-liquid-solid (VLS) growth mechanism. The atomic force microscopy, x-ray diffraction, field emission scanning electron microscopy and high resolution transmission electron microscopy were used to study the growth, structure, morphology and optical properties of the nanowires. High emission current density of 1.5 mA/cm2 under the field of 8.5 V/μm and low turn-on field of 0.83 V/μ at current density of 25 μA/cm were observed.
