“…Electrochemical analysis of the nanocomposite based EMD is investigated for ± 1.5V with 50mV/s scan rate in 1M Ferrocene of 98% purity. Cyclic voltammetry analysis is carried out which signi es that the redox response for both bleaching and colouration condition takes place within the nano-membranes of the electrochemical cell [22,23,24]. This initiates the quantum tunnelling process due to carrier transportation in the EMD.…”

Nanocomposites based Electrochromic Membrane Device (EMD) is fabricated by using DC sputtering with differently doped nanomembranes WO3 doped Ag NW and Li+, PEO, and H+Nb2O5 which undergoes optical and electrochemical characteristics so as to be capabale for smart applications. Highest bleaching transmittance of this device is evaluated to be 96.1% at 549nm and 93.1% at 825nm in the visible and IR spectra. Average colouration transmittance is observed to be 11.1% over visible range and 2.6% over IR range. A comparison with existing devices are also studied and analysed to understand the benefit of the EMD device. Dimming fastness of EMD on 500, 550 and 600nm upon a certain wavelength counted as 105, 111 and 150sec, respectively. Both transmittance modulation and optical density are also computed as 85% and 0.94. Cyclic voltammetry of each film and the whole nanostructured device arrangement is carried out for 50mV/s over +1.5V to 1.5V in the standard environment, which overlayed the understanding of the quantum tunnelling and carrier confinement effects in the device that leads to enhanced device performance. Whole experimentation of EMD stands out as an imperative accomplishment for standard requirements to be fit for future smart applications.

“…[5][6][7][8][9][10] Therefore, MoO x films are widely used in many fields. There are various methods for preparing MoO x thin films, commonly used are spray pyrolysis, [11,12] pulsed molecular laser deposition, [13,14] sol-gel method, [15,16] sputtering, [17,18] etc. However, the films prepared by these techniques often have the problems of poor uniformity, lack of smoothness, and low repetition rate.…”

Herein, we construct amorphous molybdenum oxide films by thermal atomic layer deposition (T‐ALD) and plasma enhanced atomic layer deposition (PE‐ALD). The physical and chemical properties of molybdenum oxide films prepared by the two methods were systematically compared by means of film growth law, atomic force microscope and scanning electron microscope etc. The results show that the amorphous molybdenum oxide physical phase prepared by both atomic layer deposition methods is MoO3. Compared with T‐ALD MoO3, the growth rate of MoO3 thin films prepared by PE‐ALD is higher. Compared to PE‐ALD MoO3, the MoO3 films prepared by T‐ALD did not have nucleation delayed to a laminar growth mode, resulting in smoother deposited films and contained less impurity carbon. The MoO3 prepared by PE‐ALD contains 7.4% impurity carbon. This carbon‐doped film significantly improves the conductivity of the MoO3 film and shows good electrochemical activity. As expected, the MoO3 films prepared by PE‐ALD show good electrocatalytic oxygen evolution reaction. The overpotential was only 259 mV at 10 mA cm‐2 and continued to evolution oxygen for 60 h with almost no attenuation, indicating that carbon doping significantly improves the catalytic intrinsic activity and stability of MoO3.This article is protected by copyright.

“…In addition, physical methods could also yield the uniformly monodisperse metallic NPs without solvent contamination. Thermal deposition [ 31 , 32 ], sputtering deposition [ 33 – 36 ], electron beam evaporation [ 37 – 39 ], and pulsed laser deposition (PLD) [ 40 – 43 ] are some of the most commonly used physical methods to produce the metallic NPs. Mechanical pressure, high-energy radiation, thermal energy, and electrical energy have been applied to generate the metallic NPs by triggering the melting, evaporation, condensation, and ablation [ 28 ].…”

Graphical abstract Metallic nanoparticles (NPs), as an efficient substrate for surface-enhanced Raman scattering (SERS), attract much interests because of their various shapes and sizes. The appropriate size and morphology of metallic NPs are critical to serve as the substrate for achieving an efficient SERS. Pulsed laser deposition (PLD) is one of the feasible physical methods employed to synthesize metallic NPs with controllable sizes and surface characteristics. It has been recognized to be a successful tool for the deposition of SERS substrates due to its good controllability and high reproducibility in the manufacture of metallic NPs. This review provides an overview about the recent advances for the preparation of SERS substrates by PLD technique. The influences of parameters on the sizes and morphologies of metallic NPs during the deposition processes in PLD technique including laser output parameters, gas medium, liquid medium, substrate temperature, and properties of 3D substrate are presented. The applications of SERS substrates produced by PLD in the environmental monitoring and biomedical analysis are summarized. This knowledge could serve as a guideline for the researchers in exploring further applications of PLD technique in the production of SERS substrate.
