“…Several techniques for the deposition of AuNPs have been reported in the literature. [ 20–40 ] Selecting the best‐suited deposition technique depends on the size, shape, and surface coverage of the medium in which the nanoparticles are present as well as the carrier material. One of the major difficulties is to achieve a macroscopically large homogeneous deposition area of nanoparticles with minimal clustering.…”

“…This problem also excludes the use of wet-chemical deposition techniques such as electrochemical, galvanic, electrophoretic, or chemical bath deposition that are based on a chemical reaction in which reactants combine to form a product and thereby coat a surface. [23,31,32] As these take place in a solution, they are unsuitable for the same reason as the LB-technique described above.…”

Electron emission cross sections of gold nanoparticles (AuNPs) are important for assessing their radiosensitizing effects from ionizing radiation using Monte Carlo simulations. Measurements of these data require samples of sufficiently large area density, homogeneous nanoparticle distribution, and a mechanically stable sample holder to ensure a low background signal. While several methods exist for the deposition of nanoparticles, there is little information regarding the deposition of AuNPs in an aqueous solution onto a self‐supporting film. The aim of this is to find suitable preparation techniques for AuNP samples which fulfill the above requirements. AuNP samples are produced using different deposition techniques and a 50 nm‐thick carbon foil as the substrate. These samples are characterized with respect to the size and spatial distribution of AuNPs using a scanning electron microscope. The drop‐casting technique yields the best results, while those obtained with the spin‐coater technique are less reproducible regarding sample stability. The microdrop method is deemed unsuitable due to its tendency to form AuNP clusters. Measurements conducted with a synchrotron radiation source, as well as with protons and electrons, confirm the suitability of these samples for studying electron emission spectra of AuNPs for different radiation types.

“…Experiments show that to achieve high quality films, the size of NPs should be as uniform as possible. According to our previous experiments, the synthesis parameters such as the laser fluence and repetition rate as well as the deposition parameters were selected to provide optimal conditions for the synthesis of gold NPs with uniform size [7,14,15]. The crystalline structure and optical properties of the gold NPs and prepared thin films were respectively studied by a STOE X-ray diffractometer with Cu-K α radiation and a UV-Vis-NIR spectrophotometer from PG instruments (T-80).…”

Effects of the deposition time and voltage on the characteristics of gold nanoparticles (NPs) thin films, prepared by the electrophoretic deposition (EPD) method on the silver substrate, were investigated experimentally. Au NPs were synthesised using the pulsed laser ablation method in distilled water. The suspended solution of the gold NPs was used as the electrolyte of EPD. An irradiation was carried out by the fundamental wavelength of a Q‐switched NdYAG laser at 1064 nm and 7 ns pulse width. The electrophoretic deposition apparatus consisted of two 2 × 2 cm pieces of silver plates as the electrodes. They were immersed in parallel with a 7 mm gap in the gold NP suspension. Five samples of gold NP thin films were prepared at different deposition times and applied voltages. Results show that the roughness, thickness and surface quality of EPD prepared thin films can be strongly controlled by the deposition time and applied voltage. The thickness of deposited films was dependent on the voltage of deposition in which their roughness was increased with increasing the deposition time. Furthermore, the reflection of deposited films was affected by the surface roughness.

“…Nanotechnology is the dominant technology in today's world because of the scope of tailoring of the functionalities by altering the size, shape or constitution of nanomaterials [1][2][3]. The optimization of nanoparticle synthesis, therefore, has attracted a lot of attention as it is the prime tool in controlling the morphology of synthesized nanoparticles [4][5][6][7]. Silver nanoparticles are one of the most widely researched nanoparticles because of their wide applicability in fields such as biomedical applications [8], catalysis [9], electronics [10] and in antimicrobial applications [11][12][13][14].…”

Spherical silver nanoparticles of required size were synthesized employing a seed-mediated approach using leaf extract of Azadirachta indica. Reaction pH was used to manipulate the rate of reduction of the precursor salt for achieving a fast rate of reaction needed during the synthesis of silver nanoparticles seeds and a slower rate of reaction needed for controlled growth and inhibition of secondary nucleation. A mathematical model was developed for staggered growth of silver nanoparticles using a multi-step growth approach. The developed model was used to predict the size of silver nanoparticles after various growth steps and was compared with the experimentally achieved results. Transmission electron microscope images were used for the determination of the size of the synthesized silver nanoparticles. The mathematical model appears to be a promising tool in enabling real-life application of green synthesized silver nanoparticles.
