pH-Dependent Single-Step Rapid Synthesis of CuO and Cu<sub>2</sub>O Nanoparticles from the Same Precursor
A single-step protocol
to prepare Cu<sub>2</sub>O and CuO nanocrystalline
particles from the same precursor by microwave irradiation has been
developed using the pH of the solution as the only variable parameter.
The utility of different bivalent Cu-precursors for synthesis of CuO
and Cu<sub>2</sub>O nanoparticles was also investigated. The morphology,
phase purity, and optical properties of these nanoparticles were analyzed
using TEM, SEM, XRD, and optical spectroscopy. The band edges were
determined using cyclic voltammetry. Field effect transistors based
on CuO nanoparticles showed a hole mobility of 3.5 × 10<sup>–2</sup> cm<sup>2</sup> V<sup>–1</sup> s<sup>–1</sup>, making
them a suitable candidate for energy-related applications. The effect
of hydrazine vapor exposure on the IV-characteristics of CuO nanoparticles
was also investigated. This revealed a decrease in source current
with respect to time
