Synthesis by sol–gel process, structural and optical properties of nanoparticles of zinc oxide doped vanadium

Facile Green Synthetic Route to the Zinc Oxide (ZnONPs) Nanoparticles: Effect on Green Peach Aphid and Antibacterial Activity

“…These application led many researchers to develop different routes to synthesis zinc oxide nanoparticles such as chemical route (Singh & Gopal, 2008;Abbasi et al, 2017), hydrothermal route (Ipeksac et al, 2013;Peng et al, 2016), sol-gel template process (Kumari et al, 2010;El Ghoul et al, 2012), photoluminescence emission technique (Rocha et al, 2014), microwave-assisted hydrothermal and decomposition (Tseng et al, 2012;Mousa et al, 2013), aerosol process (Ozcelik & Ergun, 2014), sonochemical synthesis (Zak et al, 2013), laser ablation (Thareja & Shukla, 2007), microemulsion method (Yıldırım & Durucan, 2010), precipitation method , hydrolyzed in polar organic solvents (Ehlert et al, 2014), solid-state thermal decomposition (Soofivand et al, 2013), microwave synthesis (Sutradhar et al, 2016). These routes have many disadvantages due to difficulty of scale up the synthesis process, separation and purification of nanoparticles from surfactants, co-surfactants, organic solvents, high energy consumption, and toxic by-products.…”

Photoconversion from yellow-to-green in vanadium doped zinc silicate nanophosphor material

“…In the case of undoped ZnO nanoparticles, this spectrum indicates that all the Bragg peaks are indexed in the hexagonal wurtzite structure (JCPDS Card No. and no peaks from other phases are detected [29,30]. After the doping of ZnO with vanadium and a thermal treatment, in addition to the peaks corresponding to ZnO, four secondary additional phases are detected, which can be attributed to VO 2 (1 2 0), V 2 O 3 (0 1 2), V 2 O 5 (1 0 1) and Zn 3 (VO 4 ), respectively [31].…”

In-situ sol–gel synthesis of luminescent Mn2+-doped zinc silicate nanophosphor

“…36-1451) of wurtzite ZnO structure [7,19]. The lattice constants calculated from the XRD pattern, which are very close to ZnO ones, i.e., a ¼ 3:2498Å and c ¼ 5:2066Å [20][21][22]. The average crystallite size (D) was estimated from the line broadening in X-ray powder using Scherrer's equation [23].…”
