“…The addition of silver nanoparticles in the oxide matrix is performed in transparent conductive oxide films, gas-sensing films, photocatalytic films, and antibacterial coatings [24][25][26]. On the other hands metal/metal oxide multilayer play an important role in the micro-and nanoelectronics and optoelectronics [24][25][26][27]. Metallic or low band gap nanoparticles serve as the nanoelectrodes [28].…”

Effect of silver thickness on structural, optical and morphological properties of nanocrystalline Ag/NiO thin films

Silver (Ag) nanolayers were deposited on nickel oxide (NiO) thin films by DC magnetron sputtering. The thickness of Ag layers was in range of 20-80 nm by variation of deposition time between 10 and 40 s. X-ray diffraction results showed that the crystalline properties of the Ag/NiO films improved by increasing the Ag film thickness. Also, atomic force microscopy and field emission scanning electron microscopy images demonstrated that the surface morphology of the films was highly affected by film thickness. The film thickness and the size of particles change by elevating the Ag deposition times. The composition of films was determined by Rutherford back scattering spectroscopy. The transmission of light was gradually reduced by augmentation of Ag films thickness. Furthermore; the optical band gap of the films was also calculated from the transmittance spectra.

“…The 933.23 eV for Cu indicates that the Cu nanoplate consist Cu and copper (II) oxide [ 14 ]. According to the Al-Kuhaili et al the NiFC composite consist Ni-O functionalities which indicates that the air gun drying caused slight oxidation of Ni nanoplate [ 15 ]. A binding energy of Fe2p located at 711.18 eV specifies that the form iron oxide has Fe 3+ while the Zn2p position implies the presence of Zn-O, and Zn-N functional groups which are from oxidation and CTAB [ 16 , 17 ].…”

The cost-effective spray coated composite was successfully synthesis and characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, and X-ray diffraction techniques. The one step synthetic strategy was used for the synthesis of nanoplates that have a crystalline nature. The composites are amorphous and hydrophobic with micron thickness (<400 m). The maximum contact angle showed by composite is 132.65° and have wetting energy of −49.32 mN m−1, spreading coefficient −122.12 mN m−1, and work of adhesion 23.48 mN m−1. The minimum thickness of synthesized nanoplate is 3 nm while the maximum sheet resistance, resistivity, and electrical conductivity of the composites are 11.890 ohm sq−1, 0.4399 Ω.cm−1, and 8.967 S.cm−1, respectively. The cobalt nanoplate coated non-woven carbon fabric (CoFC) possesses excellent sheet resistance, hydrophobic nature, and EMI shielding efficiency of 99.99964%. The composite can block above 99.9913% of incident radiation (X band). Hence, the composite can be utilized in application areas such as medical clothes, mobile phones, automobiles, aerospace, and military equipment.

“…For thermal performance characterization, the heat reflectance (ρ H ) is commonly used [1,2,10,14]. This is calculated as the fraction of the incident radiation that is reflected by the glazing in the infrared range: Fig.…”

“…In order to suppress its visible reflectance, the metal layer (M) is combined with dielectric films (D), serving essentially for antireflection purposes. Several bilayer configurations (D/M or M/D) are proven effective in enhancing the overall visible transmittance [10] and also the infrared reflectance by smoothing the metal surface [11]. Nevertheless, only the three-layer system D/M/D allows achieving maximum transmittance above 80% at wavelengths near λ = 0.55 μm (which corresponds to the human eye peak sensitivity) by a fine adjustment of the thickness for each layer [12,13].…”

Transparent heat reflectors have been prepared by DC sputtering of pure metal targets on glass substrates at room temperature. These are three-layer coatings based on a high reflective silver film surrounded by transparent tin oxide layers, which reduce greatly the silver reflection in the visible range, but not in the infrared region. In fact, such infrared reflectance has been controlled by the Ag interlayer thickness. Besides, during the tin oxide growth by reactive deposition, both the oxygen partial pressure and the sputtering time have been tuned to maximize the visible transmission while avoiding the possible Ag oxidation. In this way, optimized SnO x /Ag/SnO x coatings have been achieved with high luminous transmittance (τ L = 81% including the glass substrate) and low solar heat gain (g = 0.55), as required for energyefficient glazing applications.
