Solution-Processable Growth and Characterization of Dandelion-like ZnO:B Microflower Structures

Intrinsic and dandelion-like microflower nano-rod structures of boron-doped ZnO thin films were synthesized with an ecofriendly cost-effective chemical bath deposition technique from aqueous solution zinc nitrate hexahdyrate [Zn(NO3)2.6H2O] as a precursor boric acid doping solution. The boron concentrations 0.1, 0.3, 0.5, 1.0, 3.0, 5.0, 7.0 by volume. Scanning electron micrographs showed that appears to hinder the vertical alignment crystallites. Additionally, independent hexagonal observed coalesce together form on film’s surface. atomic ratio elements was determined via X-ray photoemission spectrum technique. There no substantial changes in vibration structure film upon terms Raman spectra. optical band gap (3.28 eV) decreased B doping. ZnO:B varied between 3.18 3.22 eV. activation energy calculated 0.051 eV, whereas containing 1.0% 0.013 eV at low temperatures (273–348 K), versus 0.072 0.183 high (348–523 respectively. Consequently, it can be interpreted 1% B-doped ZnO, which has lowest both temperatures, may find some application areas such sensors for gases solar cells.
