“…Additionally, large-scale NP production can be achieved through the use of physical and chemical processes, but these approaches come at a significant cost because they demand a lot of energy. [24,25]. Bearing in mind the restrictions of these approaches in nanomaterial synthesis, ecological approaches need to be settled utilizing procedures that are unpolluted, non-hazardous, and eco-friendly [26].…”

Silver (Ag) nanoparticles (NPs) are perceiving remarkable progress during the past few periods due to its exclusive properties in many applications. Recently, green synthesis method of NPs is racing against traditional chemical and physical methods by avoiding the use of many toxic chemicals, and expensive devices. Accordingly, in this study, dry and fresh Portulaca‐oleracea L. leaf extract has been employed for producing AgNPs as a reducing, capping and stabilizing agents. This process is simple, eco‐friendly and green. UV–vis spectra showed the formation of AgNPs represented by the change of a colorless liquid to brownish solution. The crystallinity of the AgNPs, was confirmed by X‐ray diffraction (XRD). The contribution of the available functional groups of the leaf extract in the reduction and capping process of NPs was demonstrated using Fourier transform infrared spectroscopy (FTIR). This study showed that fresh Portulaca‐oleracea L. leaf extract provides better NPs in terms of stability, purity, degree of crystallinity and spherical shape. The biosynthesized AgNPs from both procedures were coated on the indium tin oxide (ITO) glass substrates to enhance the reflectivity property. It has been shown that the utilized AgNPs, from fresh Portulaca‐oleracea L. extract, has smaller size and negligeable agglomeration, consequently lower light transmittance.

Magnetite quantum dots were synthesized by solvothermal method in a conventional reflux setup, in an inert environment, at different reaction temperatures and times. Powder X-ray diffraction patterns of the as-prepared iron oxide confirmed magnetite crystalline phases irrespective of the reaction conditions. TEM micrographs revealed that the iron oxides obtained at 200, 180 and 165 °C are spherical in shapes with mean particle sizes of 3.25, 3.3 and 3.90 nm respectively, showing an increase in particle size with decreasing temperature. TEM micrographs revealed that particles obtained at 6 and 3 h have a mean particle size of 3.25 nm while particles obtained at 4.5-h has a bigger mean particle size of 7.5 nm. The results show that irrespective of the synthetic parameters, the average particle sizes of the magnetite are in the range 3–8 nm and could be described as quantum dots. Optical absorption spectra of the as-prepared magnetite quantum dots exhibited maximum absorption in the range of 200–210 nm. Fe3O4-1, Fe3O4-2 and Fe3O4-3 synthesized at 200, 180 and 165 °C have energy band gaps of 5.49, 5.13 and 5.01 eV respectively, showing a decrease in band gap with decreasing temperature. Fe3O4-4 and Fe3O4-6 synthesized at 6 and 3 h have optical band gap of 5.44 eV while Fe3O4-5 synthesized at 4.5 h has a band gap of 3.75 eV. FTIR spectra confirmed the passivation of the surface of the as-prepared magnetite quantum dots by oleate.
