Transparent zinc oxide (ZnO) films has been cathodically deposited on conductive glasses from a simple aqueous zinc nitrate electrolyte kept at 335 K. ZnO films prepared had a wurtzite structure and exhibited an optical band gap energy of 3.3 eV which is characteristic of ZnO. A 2-μm-thick ZnO film with an optical transmittance of 72% has been deposited by electrolysis only for approximately 20 minutes at the cathodic potential of −1.0 V compared with the Ag/AgCl reference electrode.
Zinc oxide films of good quality have been cathodically deposited on NESA glasses from aqueous 0.03 to 0.1 mol/liter zinc nitrate electrolyte at 335 K.The films had a wurtzite structure and an optical bandgap energy of 3.3 eV which is characteristic of ZnO.
Transparent zinc oxide (ZnO) films had been chemically deposited on nonconductive glass from aqueous solutions containing zinc nitrate and dimethylamine-borane (DMAB) kept at 323 K. The ZnO films had a wurtzite structure and exhibited an optical bandgap energy of 3.3 eV which is characteristic of ZnO. A 0.2 m thick ZnO film with an optical transmittance of 80% was deposited by immersion for approximately 20 mm in an aqueous solution containing 0.05 mol/liter zinc nitrate and 0.05 to 0.1 mol/liter DMAB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
