“…Lorentz method was used to analyse the full width at half maximum via magic plot software and Siemens d5000 X-ray diffractometer Eva software. Silver thin films yielded grain size of 27.52nm, 30.12 nm and 32.88nm for Ag deposited at 250W, 300W and 350W respectively similar to Todorov et al report [15]. The increase in grain sizes with sputtering power signify increase in crystallinity of the silver thin films [15].…”

“…Moreover, while sputtering power increases, the (111) peak intensity becomes stronger as shown in Figure 1(a). This implies an increase in crystallinity and grain size, with (111) plane having the lowest surface energy [13,15,18]. The grain size of the silver film is an important indicator of the crystallization quality, which was calculated using the Scherrer formula.…”

We present an investigation into the pseudo-capacitive energy storage potential of silver (Ag) and silver oxide (Ag 2 O) thin film electrode materials prepared by reactive magnetron sputtering. The growth mode and morphology of the prepared films were investigated using the scanning electron microscope (SEM), which reveals columnar growth structure and microporous sites. The stoichiometry and oxidation states of the silver oxide films were monitored with X-ray diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS) and Fourier transform infra-red spectroscopy (FTIR). The XRD results reveal the nanocrystalline nature of the silver and silver oxide thin films with peak intensities indexed at (111) planes. Static and dynamic Contact angle measurements were used to probe the penetration of the aqueous NaCl electrolyte into the pores in the prepared silver and silver oxide films, with surface wettability of all (Ag) and (Ag 2 O) thin films hydrophilic in nature, which is vital for a good electrochemical performance. The Faradaic redox reactions, capacitance and the charge discharge of the films when exposed to the NaCl electrolyte, were monitored with cyclic voltammetry and chronopotentiometry charge-discharge. Results show that Silver and silver oxide

“…This is attributed to its high electrical conductivity, color‐neutral transmission in the visible range of the spectrum and low refractive index . Recently, Ag thin films and nanostructures have received renewed interest for industrial applications due to their easy preparation and lower cost in comparison to gold (Au) and Platinum (Pt) nanoparticles . It is important to obtain ultrathin Ag film which has as conductive as possible for maximize transmission in the visible and reflectance in the infrared range.…”

In this work, continuous and conductive ultrathin Ag films with highly infrared reflective and highly visible transmittance were achieved using several metal seeds (Ti, Nb, Cr, Ni, Mo, Pt, Cu, and Ru), having ~1‐2 nm in thickness, deposited between Ag and dielectric AZO layers on glass substrate by magnetron sputtering with confocal target geometry. The optical properties in the visible and infrared ranges and conductivity of Ag/M‐seed/AZO/glass structures were compared in order to determine the influence of the seeds. It was observed that all M‐Seeds increased both visible transmittance and infrared reflectance. But also, it was shown that Nb and Ti seed layers which help on coalesced of Ag and AZO layers are more effective on the electro‐optical characteristics of the Ag thin films than the other seeds. Ag/Nb/AZO/glass and Ag/Ti/AZO/glass structures showed 2.81 and 2.84 Ω/□ sheet resistance and low surface roughness, respectively, which are the best film structures. In addition, these films have homogeneous and defect‐free surfaces that do not cause any electrical breakdown. Besides, Nb and Ti seeded structures have the low‐emissivity both 780‐2500 nm and long wavelength (λ > 3 μm) spectral region as 0.0357 and 0.0361, respectively.

Low‐Temperature Sn⁰ Nanoparticles Synthesis by Means of Tin(II) N,N‐Complexes Reduction

et al. 2021

View full text Add to dashboard Cite

A novel low‐temperature liquid phase synthesis of the Sn0 nanoparticles has been reported. The effect of different reducing agents (Li[AlH4], K[BEt3H], Na[BH4]) on the reduction of the two different N,N‐coordinated SnII complexes has been described. The influence of the different imino‐pyridine chelating ligands to the synthesis of the Sn0 particles, their separation and the usage of surfactant for resuspendation to nanocolloid has been studied. The Sn0 nanoparticles were studied by means of Energy‐dispersive X‐ray spectroscopy, powder X‐ray diffraction, atomic force microscopy and dynamic light scattering from the point of view of the chemical composition, crystallinity and size/agglomeration behavior.
