Synthesis and characterization of zinc aluminum oxide thin films by sol–gel technique

Thin film of ZnAl2O4:Eu3+ synthesized by a non-alkoxide precursor sol-gel method

“…4,5 Bulk non-doped ZnAl 2 O 4 has been prepared by the sol-gel process employing alkoxides as precursors, as well as by coprecipitation and wet mixing. 6,7 Phani et al 8 have obtained ZnAl 2 O 4 thin films by utilizing an alkoxide solgel route and deposition by spin-coating. Davolos et al 9 have successfully prepared bulk zinc aluminate by a nonalkoxide sol-gel method.…”

Synthesis and characterization of spinel-type CuAl2O4 nanocrystalline by modified sol–gel method

“…Transition metal aluminates are commonly prepared by a solid state reaction [7], coprecipitation method [8,9], hydrothermal [10][11][12], combustion [13] and sol-gel [14][15][16][17][18][19][20][21][22]. The disadvantages of solid-state routes, such as inhomogeneity, lack of stoichiometry control, high temperature and low surface area, are improved when the material is synthesized using a solution-based method.…”

Synthesis and Characterization of Zn(1-x)NixAl2O4Spinels as a New Heterogeneous Catalyst of Biginelli's Reaction

“…[10][11][12] Oxides spinels are usually synthesized by solid state reaction at high temperature, 14,15 sol gel, coprecipitation and hydrothermal methods are also used to prepare spinels at low temperature. [16][17][18][19] The coprecipitation method is reproducible, permits good stoichiometric control, and produces pure nano sized powders with high surface area. For these reasons, it becomes the most attractive technic.…”
