“…The key point is that the overall copolymer unit size is used as the base for the experiment results. 59 By comparison, the experimental approach for the absorption (Figure 7A) and curve performance of the CASTEP simulation process (Figure 7B), it can be settled that, This is attributed to an atomic surface state induced by the ordered positions of the copolymer gaseous phase. 60,61 The measured data is applied from the Abs.…”

A crystalline and conjugated semiconductor thin film of poly(o‐phenylene diamine‐co‐m‐phenylene diamine) copolymer [PoPmP]TF with a thickness of 150 ± 3 nm is fabricated by physical vapor deposition technique (PVD). The copolymer is produced in an acidic solution using oxidative polymerization method. The ratio between the monomers and initiator is 1:1:2. The characterization of the obtained copolymer powder is carried out using different techniques includes Fourier‐transform infrared spectroscopy (FTIR), UV–Vis spectroscopy (UV–Vis), proton nuclear magnetic resonance (1HNMR), X‐ray diffraction analysis (XRD), and scanning electron microscopy (SEM). The structure and optical properties of the thin film were measured experimentally and computationally using DFT simulation. The obtained DFT data provide good proof for the electronic transition in zero‐dimensional [PoPmP] as a single crystal molecule. The obtained thin film presented encouraging outcomes to be a worthy applicant for polymer solar cell uses. This study provides valuable information on the nature and sources of defect formation and electronic transition in conducting doped copolymer which open the way for the application as an optoelectronic device.

“…doped NiWO4 nanostructures showed an excellent absorption in the UV region around 250 to 400nm with the shoulder peak occurred at 450nm. The absorption band appeared at 450nm is mainly due to transition of electron from 3 A2g to 1 Eg [20]. The occurrence of absorption in the UV region is mainly due to excitation from O2p to Wt2g in the (WO4 2-) group and the peak appeared in the visible region is due to charge transfer of oxygen 2p atom to one of the empty 5d orbital of tungsten.…”

NiWO4 nanostructures doped with different ratios of Eu3+ have been prepared by a chemical precipitation method. The influence of Eu3+ on NiWO4 nanostructures were characterized using X-ray diffraction (XRD), UV-visible diffuse reflectance spectra, scanning electron microscopy (SEM) and Raman. XRD patterns display that the samples crystallize to monoclinic wolframite structure. SEM images reveal that the particles are well uniformly dispersed with average particle size lies around 40-50nm. Third-order nonlinear optical properties were studied by a Z-scan technique at 532 nm using continuous wave diode pumped Nd:YAG laser. Open and closed aperture results reveal the nanostructures to possess reverse saturation absorption and negative nonlinear refraction. The calculated absorption coefficients (β), imaginary part of third-order susceptibilities Imχ(3) are in the order of 10-6(cm/W) and 10-7 esu. These results indicated that the synthesized nanostructures could be promising materials for optical device applications.

The green synthesis of nano-silver (NS) has gained increasing attention owing to its cost-effectiveness and environmental friendliness. Herein, we have described a novel one-step green preparation method of stable NS aqueous solution using Tollens reagent as the silver ion source, D-fructose as the reduction agent, and polyvinyl pyrrolidone (PVP) as the stabilizing and capping agent. The optimum preparation parameters were 40 mL 10 g L−1 PVP, 100 mL 0.116 mol L−1 D-fructose, and 200 mL 0.001 mol L−1 Tollens at a reaction temperature of 25 °C for 2 h. The prepared NS solution had a pH value of 7.10, with approximately spherical NS particles in the range of 13.95–87.36 nm. The resulting NS solution was stable under normal temperature, boiling water bath, and acidic environment; however, it did not exhibit stability under an alkaline environment. The NS solution had a remarkable absorption peak at 410 nm in its ultraviolet visible spectrum. Moreover, it exerted strong inhibitory effect on the growth of the bacteria isolated from the vase water of cut carnation ‘Prince’ flowers. These findings indicate that the obtained NS aqueous solution is potentially a practical and effective antibacterial agent for preserving cut carnations and other cut flowers.
