“…The ZnS material doped with metals exhibits excellent luminescent properties when excited by ultraviolet ray, X-ray, cathode ray or electrical current [1]. In the area of optics, because of its high refractive index (2.35), ZnS is used as a reflector [4] or as a part of a double layer antireflective (AR) coating, if used in conjunction with a low refractive index material, and because of its high transmittance in the visible range, it is used as a dielectric filter [5,6]. ZnS is highly suitable as a window layer in hetero-junction photovoltaic solar cells and as * E-mail: r.v.zaware@gmail.com a buffer layer in CuInSe (CIS) and Cu(In,Ga)Se 2 (CIGS) based solar cells; because the wide band decreases the window absorption loses and improves the short circuit current of the cell [7,8].…”

Zinc sulphide (ZnS) thin films were prepared by improved spray pyrolysis (ISP) method. The ISP parameters, such as carrier gas flow rate, solution flow rate and substrate temperature, were controlled with an accuracy of ±0.25 lpm, ±1 ml/h and ±1°C, respectively. The solution was sprayed in a pulsed mode. The substrate temperature was optimized by analyzing substrate temperature dependent properties of thin films. The thin film deposited at a temperature of 450°C was dense and fairly smooth with satisfactory crystallinity and very small impurity content. The effect of precursor ratio in the solution on structural, compositional and optical properties of thin ZnS films, deposited at a temperature of 450°C, was studied. A gradual increase in band gap energy from 3.524 eV to 3.634 eV, refractive index from 2.5 to 2.9 and dielectric constant from 6.6 to 8.7 were observed with the variation of solution precursor (Zn:S) ratio from (1:2) to (1:6). The structural and compositional studies support this kind of enhancement in optical properties. The results show that the thin ZnS film prepared by ISP at the substrate temperature of 450°C from a solution with specific precursor ratio can be used for optoelectronic and photovoltaic applications.

Highly (002)‐oriented Al‐doped zinc oxide (AZO) thin films with the thickness of less than 200 nm have been deposited on an oxygen‐controlled homo‐seed layer at 200 °C by DC magnetron sputtering. With the homo‐seed layer being employed, the full‐width at half maximum (FWHM) of the (002) diffraction peak for the AZO ultra‐thin films decreased from 0.33° to 0.22°, and, the corresponding average grain size increased from 26.8 nm to 43.0 nm. The XRD rocking curves revealed that the AZO ultra‐thin film grown on the seed layer deposited in atmosphere of O2/Ar of 0.09 exhibited the most excellent structural order. The AZO ultra‐thin film with homo‐seed layer reached a resistivity of 4.2 × 10–4 Ω cm, carrier concentration of 5.2 × 1020 cm–3 and mobility of 28.8 cm2 V–1 s–1. The average transmittance of the AZO ultra‐thin film with homo‐seed layer reached 85.4% in the range of 380–780 nm including the substrate. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…These include the use of surfactants (Ortiz Landeros et al 2012;Zhang et al 2009), emulsification (Binks et al 2010;Noshirvani et al 2017) external forces (Bandekar et al 2014;Guo et al 2016;Sauter et al 2008) and the use of substrates (Miao et al 2007;Zhang, Xue and Wang 2002). In principle, nanoparticles synthesized on substrates will be fixed in space and agglomeration can be prevented (Sun and Sirringhaus 2006).…”

Enhanced photocatalytic activity of ZnO nanoparticles grown on porous silica microparticles

et al. 2017

ZnO nanoparticles (NPs) have been synthesized on porous silica microparticles, namely sand microparticles using the sol-gel technique. The ZnO NPs grown on the multifaceted surface of porous silica microparticles were applied as photocatalyst for the degradation of methylene blue (MB) in aqueous solution. The enhanced rate constant observed was due to two reasons. Firstly, the multifaceted surface of the sand substrate provided fixed space for growth space which prevented agglomeration of the ZnO NPs photocatalyst, thus maintaining a large surface area. Secondly, the presence of nanopores on the sand surface provided adsorption sites for MB molecules to be in the vicinity of the photocatalyst. The photocatalytic activity was significantly enhanced where photodegradation efficiency of supported ZnO NPs reached 71.7% compared to 48.2% for unsupported ZnO NPs under UV light irradiation within 150 min. The values of k increased from 4.3 9 10 -3 min -1 to 8.6 9 10 -3 min -1 for unsupported and supported ZnO NPs, respectively.
