“…6. Existence of absorption bands at 534 cm −1 , 541 cm −1 and 535 cm −1 can be assigned to the stretching vibration of Cu-O, that is in agreement with former studies [1,16]. The peaks in the range of 1000 cm −1 to 1400 cm −1 and 1630 cm −1 to 1650 cm −1 , can be assigned to the bending modes vibration of O-H and H-O-H, respectively [17,18].…”

“…Cupric oxide (CuO) is a p-type semiconductor, having a band between of 1.21 and 1.51 eV and monoclinic crystal structure. Cuprous oxide (Cu 2 O) is also a p-type semiconductor having a band gap of approximately 2.0 eV and a cubic crystal structure [1]. Cupric oxide is one of the most important semiconductors with many applications, such as diodes, cathodes in lithium batteries, catalysis, lithium-copper oxide electrochemical cells, field emission devices, gas sensors and so on.…”

Copper (II) oxide thin films were prepared by spray pyrolysis method on soda-lime glass substrates using copper acetate precursor solution. Influence of substrate temperature on structural and optical properties was investigated. Structural analysis of these layers were carried out by X-ray diffraction (XRD). Single phase nature and high crystallinity of CuO nanostructures were observed on XRD patterns. The general appearance of the films was uniform and black in color. FT-IR transmittance spectra confirmed the results from the XRD study. Selective solar absorber coatings of copper oxide (CuO) on stainless steel substrates was prepared by spray pyrolysis method. Effect of deposition temperature on optical properties of thin films was investigated. Optical parameters, absorbance (α) and emittance ( ) were evaluated from reflectance data. It can be deduced that the porous structure, such as a light traps, can greatly enhance absorbance, while the composition, thickness and roughness of thin films can greatly influence the emissivity. Single phase nature and high crystallinity of CuO nanostructures were observed by XRD patterns. Solar absorbance of thin films were in the range of 85 % to 92 %.

“…The material is a direct bandgap semiconductor. It couples a narrow band gap (Eg = 1.2 eV -1.8 eV) [10][11][12] with a set of properties such as high-temperature superconductivity and good photoconductivity and photochemical properties [13]. This largely explains the growth of applications in the last years in the more diverse fields such as solar cells [14], gas sensors [15], field emission (FE) emitters [16], and lithium ion battery electrode materials [17].…”

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.

“…Each of these methods has its own advantages and disadvantages. In most of these studies, a mixture of phases of Cu, CuO and Cu 2 O is generally obtained and this is one of the nagging problems for non-utilizing Cu 2 O as a semiconductor (Papadimitropoulos et al, 2005). Pure Cu 2 O films can be obtained by oxidation of copper layers within a range of temperatures followed by annealing for a small period of time.…”
