Optical properties of ZnO nanoparticles synthesized by varying the sodium hydroxide to zinc acetate molar ratios using a Sol-Gel process.
Dejene, Francis B.; Abdub, G. Ali; Swart, Hendrik C.; Botha, Reinhardt J.; Roro, Kittesa; Coetsee, Liza; Biggs, Mart M. (Springer, 2016)Material property dependence on the OH−/Zn2+ molar ratio of the precursor was investigated by varying the amount of NaOH during synthesis of ZnO. It was necessary to control the water content and temperature of the mixture ... -
Wide visible emission and narrowing band gap in Cd-doped ZnO nanopowders synthesized via sol-gel route.
Leta, Jule T.; Dejene, Francis B.; Abdub, Ali G.; Roro, Kittessa T.; Hegazy, Aiat; Allam, Nageh K. (Elsevier Ltd., 2016)Cd doped ZnO nanopowder (Zn1−XCdXO, 0.15≤ X ≤0.45) has been synthesized by facile sol-gel method. The X-ray diffraction (XRD) shows the powder possess polycrystalline with hexagonal wurtzite structure of ZnO without formation ...
