Photoelectrochemical and Raman characterization of In2O3 mesoporous films sensitized by CdS nanoparticles
Beilstein J. Nanotechnol. 2013, 4, 255–261, doi:10.3762/bjnano.4.27
- , Minsk 220072, Belarus 10.3762/bjnano.4.27 Abstract The method of successive ion layer adsorption and reaction was applied for the deposition of CdS nanoparticles onto a mesoporous In2O3 substrate. The filling of the nanopores in In2O3 films with CdS particles mainly occurs during the first 30 cycles of
- the SILAR deposition. The surface modification of In2O3 with CdS nanoparticles leads to the spectral sensitization of photoelectrochemical processes that manifests itself in a red shift of the long-wavelength edge in the photocurrent spectrum by 100–150 nm. Quantum-confinement effects lead to an
- increase of the bandgap from 2.49 to 2.68 eV when decreasing the number of SILAR cycles from 30 to 10. The spectral shift and the widening of the Raman line belonging to CdS evidences the lattice stress on the CdS/In2O3 interfaces and confirms the formation of a close contact between the nanoparticles
Characterization and properties of micro- and nanowires of controlled size, composition, and geometry fabricated by electrodeposition and ion-track technology
Beilstein J. Nanotechnol. 2012, 3, 860–883, doi:10.3762/bjnano.3.97
- containing Zn(NO3), Co(NO3), nitric acid, and polyvinylpyrrolidone (PVP) as an additive, 300 nm diameter Zn1−xCoxO nanowires with x ranging from 0.01 to 0.05 were grown [94]. The synthesis and properties of semiconducting CdTe and CdS nanowires are being investigated for their potential in photodetector and
- photovoltaic applications. CdTe and CdS rods are mostly synthesized by chemical vapour deposition, and sol–gel processes. Electrodeposition of stoichiometric CdTe nanowires with diameters between 80 nm and 1 μm was reported by Enculescu et al. [95]. In addition to SEM, TEM, EDX, and XRD characterization, they
- . Polyvinylpyrrolidone (1 g/L) was added as a wetting agent. A Pt foil and a SCE acted as counter and reference electrode, respectively. The potentiostatic electrodeposition of CdS nanowires by using an electrolyte solution containing CdCl2 and thioacetamide, at 70 °C was reported by Mo et al. [99]. Finally, due to its
Junction formation of Cu3BiS3 investigated by Kelvin probe force microscopy and surface photovoltage measurements
Beilstein J. Nanotechnol. 2012, 3, 277–284, doi:10.3762/bjnano.3.31
- to be developed. We present an investigation of the Cu3BiS3 absorber layer and the junction formation with CdS, ZnS and In2S3 buffer layers. Kelvin probe force microscopy shows the granular structure of the buffer layers with small grains of 20–100 nm, and a considerably smaller work-function
- distribution for In2S3 compared to that of CdS and ZnS. For In2S3 and CdS buffer layers the KPFM experiments indicate negatively charged Cu3BiS3 grain boundaries resulting from the deposition of the buffer layer. Macroscopic measurements of the surface photovoltage at variable excitation wavelength indicate
- photovoltaic active interface with a SPV of ~130 mV [7]. It is well known from the Cu(In,Ga)Se2 solar cells that a buffer layer is required between the n-ZnO window and the p-type absorber layer to reach high efficiency values [8]. Traditionally, CdS deposited by chemical bath deposition (CBD) has been used as

Extended X-ray absorption fine structure of bimetallic nanoparticles
Beilstein J. Nanotechnol. 2011, 2, 237–251, doi:10.3762/bjnano.2.28
- several examples can be found for EXAFS analysis on nanoparticle systems, e.g., Co [8], CdS [9], CdSe [10], SnO2 [11] and Au [12] nanoparticles, as well as Ag nanoparticles embedded in glass [13][14]. To discuss the advantages and possible drawbacks of EXAFS analysis in nanoparticulate systems, this paper
Schottky junction/ohmic contact behavior of a nanoporous TiO2 thin film photoanode in contact with redox electrolyte solutions
Beilstein J. Nanotechnol. 2011, 2, 127–134, doi:10.3762/bjnano.2.15
- second band structure whose Efb lies near the redox potential of the iron complex on the TiO2 surface. The photocurrents increased with repeated scans. In a previous paper [14] by one of the present authors (MK), both Schottky junction and ohmic contact behavior were found at a single crystal CdS
- photoanode with RuO2 fine powder attached to the surface and coated with a thin film of polymer-pendant Ru(bpy)32+ on top of the RuO2. It was clear that the CdS formed a Schottky junction with the redox electrolyte solution, and in addition, the RuO2 formed an ohmic contact with the CdS, and the coated
