Thin films of CuO having an average thickness of 720 nm were deposited on clean glass substrates using the Aqueous Chemical Growth (ACG) method with Cu(NO 3 ) 2 and C 6 H 12 N 4 as precursors and annealed at different temperatures in order to determine the effect of annealing temperature on their optical and solid state properties. The study was carried out using Rutherford Backscattering (RBS) spectroscopy for t thickness and chemical composition, X-Ray Diffraction (XRD) for crystallographic structure and a UV-VIS spectrophotometer for spectral analysis. The results indicate that the absorbance and absorption/extinction coefficient of the films vary inversely with annealing temperature while the transmittance, reflectance, direct band gap, real/imaginary dielectric constants and refractive index vary directly with annealing temperature. The results further indicate an improvement in crystallinity as annealing temperature increases. The as-deposited and annealed ACG CuO thin films were found to be suitable for use as window layer in solar cells among other electronic and optoelectronic applications.

“…To investigate for those effects and for possible applications, nanostructured copper oxides have been synthesised in several shapes such as 3 nanobelts [25], nanorods [26], nanowires [27], and nanoribbons [28]. Several techniques, ranging from reverse micelles microemulsions [29], electrochemical and sonochemical deposition [30,31], chemical vapour deposition [32], alcoho-thermal and hydrothermal synthesis [33,34], thermal decomposition [35] and high-temperature synthesis [36] are available to produce such non-equilibrium morphologies.…”

Copper oxide (CuO) nanorod-like structures made of spherical nanocrystals were synthesized at moderate temperature (80°C) starting from CuCl 2 •2H 2 O crystals in a water/n-heptane microemulsion stabilised by the nonionic Brij-30 surfactant. Whole Powder Pattern Modelling of the X-ray diffraction pattern shows absence of linear and planar defects with crystalline domains in the range of 4 -8 nm. A linear correlation between the average size of the particles and the quantity of water in the system was observed: all synthesised specimens show a large blue shift of the energy bandgap (up to 2.7 eV versus 1.2 eV of bulk CuO) resulting from quantum confinement effects. The mechanism of growth of the spherical nanoparticles into nanorod-like structures has been elucidated.

“…In particular, the hierarchical structure is one of the important forms among various morphologies [5,6]. Recently, copper oxide-nanostructured materials, such as: nanorods [7], nanowires [8], nanoribbons [9] and nanobelts [10], have attracted considerable attention due to their fundamental importance and potential future applications.…”
