“…[15] used a sol-gel method to synthesis and study ZnO NPs. [16] carried out green synthesis of nanoparticles by biological systems they reported peaks absorption around 350 nm due to large excitation binding energy at room temperature. ZnO nanoparticles was blended with a poly-3-hexyl-thiophene as active material for high performance solar cell by [17,18] blended ZnO.NPs with P3HT and an improvement was reported in interchains and intrachains ordering when compared to pure P3HT.…”

Efforts has been intensified in the field of research for nanomaterials to bridge the gap for energy supply in this century. A plant-based material that may provide solutions to the current energy crisis may be found in nanomaterials. Green synthesis of nanoparticles using plant extract is gaining importance as an alternative to conventional chemical and physical method of synthesis, because of its simplicity and environmental friendliness. In this research we synthesized Zinc oxide nanoparticle (ZnO.NPs) using plant extracts and deposited using spin-coating technique. The obtained samples were characterized by UltraViolet-Visible spectrophotometer, Fourier Transform Infra-Red spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Solar simulator for electrical properties. The maximum absorption peaks occurred at 235 nm, 250 nm, 270 nm, and 300 nm respectively but lower when compared with the bulk size that occurred at 350 nm and in the visible spectrum of the wavelength band. Band gap energy of zinc oxide nanoparticle at 500 rpm was 3.50 eV. ZnO.NPs FTIR spectrum was recorded in the range of 4000-500 cm −1 . The synthesis ZnO NPs FTIR result shows Zn-O functional group was found at low wavenumber. SEM images of the samples give information on the morphology which are spherical and granular nature. The XRD pattern of synthesized nanoparticles shows that the substances only belong to ZnO since there is no diffraction peaks of other impurities and the average grain size of the particles was estimated to be 14.7 nm. ZnO.NPs thin film device under illumination has efficiency of 0.7%. Based on electrical properties of the fabricated thin film device, the parameter shows it could be suitable for photoanode of Dye sensitized solar cell.

“…Inspired by a revolutionary lecture of Richard Feynman 'There's Plenty of Room at the Bottom᾽ the scientific community got a new thought process to miniaturize the prevailing technology and form an advanced branch of science called nanotechnology (Dhand et al, 2015).The term nanotechnology was introduced by Tokyo Science University Professor Norio Taniguchi (Chokriwal et al, 2014). Nanotechnology is an escalating technology that revolutionizes many scientific realms (Fakhari et al, 2019). Nanotechnology deals with the synthesis and applications of nanomaterials that have wide applications in material science, agriculture, food industry, medical, and diagnostics (Siddiqi et al, 2018).…”

Nanoparticles are ultrafine structures with dimensions less than 100 nm. Nanoparticles have diverse applications. There are three important methods of fabrication of nanoparticles namely physical, chemical and biological methods. Physical method is a top down strategy for the fabrication of nanoparticles. It is energy intensive and time consuming. A chemical method is simple, but is expensive and requires expensive chemicals with high purity and also involves hazards of contaminations. Biological synthesis is very simple, cheap and environment friendly, requiring no expensive chemicals, temperature and is time saving. Plants and microorganisms are commonly used in this method. These are available everywhere. In the present work we synthesized Zinc Oxide (ZnO) nanoparticles by biological method using Aspargillus niger and zinc chloride (ZnCl2) as precursors. Biogenic synthesis of metallic nanoparticles by fungi is a safe and economical process because of formation of stable and small sized nanoparticles. Fungal biomass secretes proteins which act as reducing and stabilizing agents. The synthesized nanoparticles were characterized by XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy), UV-Vis (Ultraviolet, Visible) and EDX (Energy Dispersive X-Ray) techniques. Their size was in nm range and morphology of synthesized ZnO NPs was hexagonal. The ZnO nanoparticles are one of the most versatile materials and are used in cosmetics and in Bioenergy production, as a catalyst and as antibacterial material.

“…One of the most important nanoparticle is zinc oxide (ZnO) that is widely used in industries as an additive in various products (Fakhari, Jamzad, & Kabiri Fard, 2019). The increased production of nano-products results in an increase in their release to environment, particularly aquatic environments (Keller, McFerran, Lazareva, & Suh, 2013;Skjolding et al, 2016).…”

Nanoparticles are commonly synthesized chemically and because of their risk for living organisms and environment, safer synthesis methods are highly considered. This work was carried out to evaluate the acute toxicity of zinc oxide nanoparticles synthesized from Satureja hortensis on rainbow trout (Oncorhynchus mykiss) by static bioassay test. The average weight and length of trout fish used in the study were 20±3 g and 15±2 cm respectively. Three groups of the experimented fish were exposed to different concentrations (1, 10 and 100 mg/L) of ZnO nanoparticles. All the exposed fish were daily observed and dead fishes were immediately removed and recorded. The obtained data were statistically analyzed using probit regression method. The LC50 value at 96 h was found to be 25.50 mg/L for trout fish which makes this nanoparticle as a low toxicity substance in terms of toxicity classification. According to the results lifetime reduced with increasing the concentration of ZnO. Based on the obtained LC50 for the synthesized ZnO from Satureja plant in this study and comparison with that of the chemically fabricated in others work, it was revealed that the green nanoparticles synthesis is much less hazardous and a good alternative technique.
