Kinetics controlled growth of quasi-spherical ZnO single crystal in homogeneous solutions

Hydrangea‐Like Meso‐/Macroporous ZnO‐CeO2 Binary Oxide Materials: Synthesis, Photocatalysis and CO Oxidation

“…As to pure ZnO oxide (route 1), the hydrolysis of the Zn(NO 3 ) 2 in F127 solution leads to the formation of relatively large ZnO nanoparticles with a diameter of about 13 nm (calculated from XRD results). From N 2 sorption analysis, the pure ZnO sample has limited adsorption volume of nitrogen with very small surface area and pore volume, which is similar to some reports,30,31 indicating the weak interactions between the surfactant and inorganic species. Although the F127 molecules failed to play a role as the surfactant, the interfacial polymerization of ZnO particles around the microemulsion drops composed of H 2 O, C 2 H 5 OH, and F127 micelles still happened, resulting in the elliptic morphology 30,31.…”

Sonochemical Synthesis of Er3+‐Doped ZnO Nanospheres with Enhanced Upconversion Photoluminescence

“…In the present case, Zn(NO 3 ) 2 •6H 2 O was used as precursor, TEA as complexing and precipitating agent and PEG as capping agent. TEA has the chemical formula N(CH 2 CH 2 OH) 3 , which acts generally as a weak base due to the single lone pair of electrons on nitrogen atom and accordingly could coordinate to zinc ions forming [Zn(TEA) 4 ] 2+ complex [22]. Under ultrasonic irradiation, the complex would dissociate and a part of TEA molecules would hydrolyze to build up an alkaline environment, which leads to the controlled release of free zinc ions and hydroxide ions ((1) and (2)).…”

Effects of substrate temperature on sprayed ZnO thin films optical and morphological properties in terms of Amlouk–Boubaker opto-thermal expansivity ψAB

“…It is strongly proposed [1][2][3][4][5][6][7] as an alternative to the ITO indium tin oxide and the binary compound GaAs for solar cells, UV-light emitters, and heat reflectors.…”

“…Unexpectedly, dry approaches, including spray pyrolysis technique, were not extensively applied to prepare ZnO layers [4][5][6][7]. The latter technique presents many advantages, i.e.…”
