Spinel zinc ferrite (ZnFe2O4) nanoparticles have engrossed immense attention due to its unusual amalgamation of its properties especially the magnetic properties and these properties are catered as fitting candidates in the field of electronics. Nanostructured spinel zinc ferrite particles were synthesized using scalable co-precipitation technique. The morphology, particle size and reaction pace of the nanoparticles (NPs) were fine tuned by eco-friendly technique. These NPs were characterized by UV-Visible spectroscopy (UV-Vis), photoluminescence (PL), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Transmission electron microscopy (TEM), vibrating sample magnetometer ((VSM) and Dielectric studies. The required profiles were confirmed by XRD and FTIR spectra, UV-Vis, PL spectral studies. Further these measurements divulge the significance of optical properties and the spectral parameters are used to appraise the optical constants required for fabrication. Transmission electron microscopy eventually discloses the morphological analysis of the synthesized ZnFe2O4 nanoparticle as 15 nm within the scaling limitations. Using, VSM, the magnetic behaviour of the material have been determined as a function of magnetic field at ambient temperature; the magnetic measurements well-establishes the magnetic property and disclosed to have weak ferromagnetic behaviour as the crystallite size decreases. The A.C. conductivity measurements and dielectric studies were done as a functional dependence of frequency and temperature on synthesized nanoparticles.

“…Recently, photovoltaic usage for dye sensitized solar cells has become the focus of significant research attempts [6,7]. It has been specified that the energy conversion performances of the photovoltaic sets that benefit nanocrystalline Zn 2 SnO 4 are critically dependent on the size and morphology of the materials [1,8]. There are different preparation methods and factors for synthesis of various types of nanostructures with great properties [9][10][11].…”

Zn 2 SnO 4 nanostructures were obtained via facile and rapid co-precipitation approach in presence of amines with different long chain as a novel basic and capping agents. The effect of different amines such as NH 3 , ethylenediamine, triethylenetetramine, tetraethylenepentamine on the size of Zn 2 SnO 4 nanostructures were investigated. The results demonstrated that applying the appropriate amount of organic amine could be effective in particle size control. The obtained nanostructure products were specified by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, scanning electron microscopy (SEM), transmission electron microscopy (TEM) , energy dispersive X-ray analysis (EDX) and ultraviolet-visible (UV-vis) spectroscopy. Dye sensitized solar cells (DSSC) were created by the constructed electrodes as working electrode and then were studied by current density-voltage (J-V) curve. It was found that incorporating of TiO 2 nanoparticles to optimized Zn 2 SnO 4 nanostructures has significant role on the constructed DSSCs photovoltaic properties.

“…The escalationof cost of living, is the main cause of social unrest and mass poverty, arising from the limitedness of hydrocarbon energy.This has pushed engineers, scientists and researchers to broadenthe means for exploitation of sustainable and renewable energy sources, chiefly solar power.The prime focus of researchers in the recent times has shifted towards metal and semiconductor nanoparticles owing to their superior electric, magnetic and optical properties. [1][2][3] Metal sulphides have attractive applications such as intercalation precursors (TiS 2 , TaS 2 , NbS 2 ), precursors for synthesis of high temperature superconductors (La 2 S 3 ), luminescence materials (CdS:Mn, Cu, Pb), diagnostic materials (Ag 2 S), solar energy materials (ZnS, CuInS 2 ), high-energy density batteries (TiS 2 ) and other opto-electric and magnetic applications, of which Tin sulphides, a class of IV-VI semiconductors, belong to materials which exhibit variable physio-chemical properties, such as polytypism, polymorphism and non-stoichiometry. [4] They show a variety of phases such as SnS, Sn 2 S 3 , Sn 3 S 4 , Sn 4 S 5 SnS 2 owing to the versatile coordinating characteristics of tin and sulphur.…”

Optically active, tin mono-sulphide (SnS) nanoparticles, having generic name herzenbergite, being one of the narrow band gap IV–VI semiconductors, geared up recently the attention of material scientists for its applications in photovoltaics, near-infrared detectors, and biomedical applications where strong scientific information on infrared absorption is required. Among the class of chalcopyrite semiconductors, SnS is a relatively inexpensive and non-toxic material with the nature of resource abundance for solar cell applications, having a bulk direct band gap of 1.3 eV and indirect bandgap of 1.1 eV, possessing high figure of merit such as optimum optical band gap, high optical absorption coefficient for photons and high photoelectric conversion efficiency of up to 25%. In the present work, nanostructured SnS particles of 11.75 nm were synthesized by means of a cinch hydrothermal reaction using the reagents tin chloride pentahydrate and thiourea at 200°C. The crystallinity, purity, morphology, and structural featuresof as-prepared nanoparticles were characterized by Powder X-ray Diffraction (XRD), Transmission Electron Microscope (TEM), UV-visible spectroscopy (Uv-vis), Photoluminescence spectroscopy (PL) and Fourier Transform Infra-red Spectroscopy (FTIR). XRD measurements reveal the formation of well-crystallized orthorhombic tin mono-sulphide nanoparticles which may be considered as a distorted NaCl structure. TEM observations demonstrate the morphology of the nanoparticles. The FTIR examination confirmed the existence of the vital functional groups. Absorption spectrum showed that the nanoparticles have an extensive absorption array. The optical properties determined by Uv-vis and PL measurements show that the prepared SnS nanoparticles will be an ideal candidate for photovoltaic applications.
