Synthesis of nanostructured CuxS thin films by chemical route at room temperature and investigation of their size dependent physical properties

Optical and Electrical Properties of Thin Films of CuS Nanodisks Ensembles Annealed in a Vacuum and Their Photocatalytic Activity

“…The effects determined by the crystal size in the evolution of thermodynamic, structural, spectroscopic, electromagnetic, electronic and chemical properties result in a class of materials with unusual properties, which are dependent on the size, generating significant changes in both surface and electronic properties of the materials. Considering the importance of nanocrystals in technological applications, a large number of requests of the chalcogenides in electro-and absorbing coatings [1][2][3][4][5][6][7], selective radiation filters in architectural windows [8], electrodes [9], chemical sensors [7,10], optoelectronic devices [11], thermoelectric cooling materials [12], and catalysts [13,14], among others, are expected. Numerous studies have been reported on the CuS binary system in powder, bulk, and as thin films with different compositions and properties.…”

Characteristics of Nanocrystalline ZnS thin films grown on glass with different Zn ion concentrations by CBD technique

“…A sensitive electronic balance of type A&D company limited D0001 used . The thickness can be calculated from the relation below [14] : Where t : thickness of the film ,m 1 and m 2 : weight of the substrate before and after deposition respectively , A : area of thin film and ρ : density of element. The crystal structure of the prepared films has been examined by X-ray diffractometer (XRD-6000 Shimadzu) with wavelength 1.5405Å Cukα radiation, the scanning angle varied in the range (20-60)º , current 30 mA, and voltage 40 KV.…”

Surfactant free fabrication of copper sulphide (CuS–Cu 2 S) nanoparticles from single source precursor for photocatalytic applications

“…where ''0.94'' is a constant, ''H'' is Bragg ' s angle of the particular peak under consideration and ''d'' is the crystallite size of the nanoparticles [11]. Phase purity of CuS-Cu 2 S has been confirmed by PXRD and all the peaks in powder XRD are indexed for hexagonal crystalline phase of covellite (CuS) with lattices growing mostly in the direction of 110 plane.…”

“…CuS (covellite) dispersed particles, Cu 7 S 4 -CuS hexagonal plates, Cu 9 S 5 (Digenite) octahedron, and Cu 2 S (chalcocite). In recent years CuS has been synthesized with different morphologies such as nanotubes [2], nanowires [3], nano plates [4], nano rods [5], ball-flower [6], nanoparticles [7], hollow cages [8] and hollow sphere [9] with biological sulphate reduction [10], chemical route [11], chemical vapour deposition [12], chemical vapour reaction (CVR) [13], hydrothermal method [3], electrospinning [14], sono-chemical method [15], solid state synthesis [16], liquid precipitation route [17], liquid-liquid interface [18], pressure leaching process [19], micro-emulsions [20] and self-sacrificial templates [21]. Covellite (CuS) proved to be a very fruitful nanomaterial for solar cell applications [22], photocatalytic degradation of dyes [23], as a cathode material in lithium ion rechargeable secondary batteries [24], gas sensing [25] etc.…”
