A Review on Diverse Silver Nanostructures

Nanocomposite thin film of Ag nanoparticles embedded in amorphous Al 2 O 3 on optical sensors windows: Synthesis, characterization and targeted application towards transparency and anti-biofouling

“…All four spectra consist of a transmittance band peaking at a fixed position of 315 nm and a broad absorption band covering the vis-NIR spectral domain which contains several interference fringes. The fixed transmittance band results from the minimum of the imaginary part of the refractive index of bulk Ag k Ag [23] due to Ag interband transitions from 3.83 eV (323 nm) to higher energies [24]. The transmittance band intensity gradually increases from Q1 to Q4, due to the decrease of the film thickness, attributed to the precursor consumption and hence to a declining concentration gradient from the entrance to the exit of the deposition zone in the reactor.…”

One‐Pot Colloidal Synthesis of Plasmonic Patchy Particles

“…Since silver is an inexpensive noble metal with useful catalytic, electrical and optical properties our facile single step approach to novel particles should provide advantages in many application areas. [ 18 ] The formation of silver patchy particles was achieved by dispersing dried and calcined amorphous silica spheres in a dilute solution of silver nitrate followed by the addition of a reducing agent (aqueous formaldehyde solution) and a base (aqueous ammonium hydroxide). We found that the temperature at which this reaction takes place strongly infl uences the patch morphology and yield, and thereby the optical properties.…”

Structural and Optical Properties of Li<sup>+</sup>: PVP & Ag<sup>+</sup>: PVP Polymer Films

“…Figure 5(c) shows the SEM micrographs of the silver particles are spherical shaped, well distributed without aggregation in solution with an average size of about 3 μm. Both the polymer films of EDS spectrum denotes a signal observed from the silver ions [22]. To verify the chemicals in the material, an EDAX profile has also been recorded as shown in Figures 5(d), (e) & (f).…”
