Synthesis of ZnO Nanowires via Hotwire Thermal Evaporation of Brass (CuZn)‎ Assisted by Vapor Phase Transport of Methanol

Abstract EN

Zinc oxide (ZnO) nanowires (NWs) were synthesized using vapor phase transport (VPT) and thermal evaporation of Zn from CuZn.

Time dependence of ZnO NWs growth was investigated for 5, 10, 15, 20, 25, and 30 minutes.

Significant changes were observed from the field electron scanning electron microscopy (FESEM) images as well as from the X-ray diffraction (XRD) profile.

The photoluminescence (PL) profile was attributed to the contribution of oxygen vacancy, zinc interstitials, and hydrogen defects in the ZnO NWs.

Raman scattering results show a significant peak at 143 cm−1 and possible functionalization on the wall of ZnO NWs.

Growth of ZnO NWs in (0002) with an estimated distance between adjacent lattice planes 0.26 nm was determined from transmission electron microscopy (TEM) analysis.
