“…Because of adding Zn, the Zn x Cd 1-x S has large energy gap than CdS. This makes the material much more attractive for fabrication of the solar cells [12]. The Zn x Cd 1-x S nanostructures offer a great range of tune ability for both of its band gap (from 2.42 eV for CdS to 3.6 eV for ZnS) and its lattice parameters.…”

“…Several deposition techniques such as rf sputtering [1], pulse laser evaporation [2], physical vapor deposition [3], electrodeposition [4], screen printing [5], spray pyrolysis [6], chemical bath deposition (CBD) [7,8], metal organic vapor phase epitaxial (MOVPE)/metal organic chemical vapor deposition (MOCVD) [9], successive ionic layer adsorption reaction (SILAR) [10], and molecular beam epitaxial [11] have been reported previously. Spray pyrolysis is an easy technique to develop homogeneous material.…”

“…34 However, the photo conversion efficiency depends heavily on the particle sizes and also the agglomeration of nanoparticles. Sebastian et al 35 have discussed in detail the photosensitive properties of CdS and ZnCdS nanocomposites and observed the presence of Cd deep acceptor states at 1.6 eV above the valance band and donor states located at 0.1 eV below the conduction band due to S vacancies. These impurity levels, however, act as the sensitizing centers for the enhanced photoconductivity in the nanocomposite structures.…”

Cadmium sulfide (CdS) nanoparticles of three different sizes of 1.49, 2.0, and 2.1 nm were synthesized by the chemical method using thioglycerol as a capping agent. Optical absorption, wide angle x-ray scattering (WAXS), small angle x-ray scattering (SAXS), and high-resolution transmission electron microscopy (HRTEM) measurements revealed that nearly monodispersed particles of high quality could be obtained using a simple and straightforward method used in the present investigation. The nanoparticles were further used to fabricate heterojunctions with poly-phenylene-vinylene (PPV), and currentvoltage characteristics were measured. A large forward current density of 21 mA cm )2 at 1 V is obtained for samples having the smallest average particle size and 13 mA cm )2 for the samples having the largest particle size among the samples investigated.

“…Within a wide variety of nanostructures, fullerenelike nanoclusters need special attention, because their unique properties make them useable for different applications including photocatalysis, solar cells, gas sensors, or hydrogen storage [14][15][16]. Previous studies show that (ZnO) 12 nanoclusters are the most stable hollow structure for the small cluster [17,18] and have been successfully synthesized [19].…”

A DFT study for adsorption of CO and H2 on Pt-doped ZnO nanocluster

Using density functional theory calculations, we studied structural, electronic and adsorption properties of CO and H 2 adsorption on the Pt-doped (ZnO) 12 nanoclusters. The more suitable position for the Pt atom is its lateral doping on the nanocluster surface. The lower energy gap for the Pt-doped (ZnO) 12 nanoclusters denotes that their conductivity is higher in comparison with the bare nanocluster. The results showed quite a reasonable increase in CO and H 2 gas molecules adsorption energies on the nanoclusters compared with the pristine (ZnO) 12 due to Pt doping. The sensitivity of the electronic and adsorption properties to the number of molecules was calculated as well. Upon CO adsorption on the Pt-doped (ZnO) 12 nanoclusters energy, it is better when no more than two molecules can be attached to one Pt atom, while H 2 adsorption provides at least three hydrogen molecules on Pt atom. Also, changes in electronic spectra of nanoclusters under the influence of adsorbed CO and H 2 molecules imply a decline in conductivity in such systems. These investigations proved that the Pt-doped (ZnO) 12 nanoclusters can be proposed as an approachable candidate in gas sensors for detecting CO and H 2 gas. Also, the calculation results of H 2 adsorption on Pt-doped (ZnO) 12 nanoclusters can help in consideration of the possibility of hydrogen storage media creation.
