Abstract
Heterometallic [ZnM2(OR)8]m species (M = Al, Ga ; R = C2H4OMe, C2H4NMe2) were prepared and characterized by elemental analysis, FT-IR and multinuclear NMR (1H, 13C, 27Al). Their Hydrolysis was investigated. The powders were analysed by FT-IR, TGA/TDA and XRD. [ZnGa2(OC2H4OMe)8]2 allowed to obtain ZnGa2O4 at 300°C. Particles size in solution and aging phenomena were analysed. Stable colloidal suspensions (150 - 200nm) for elaboration of thin films by spin-coating techniques were obtained. These films transparent and were characterized by XRD, XPS, TMAFM, SEM, EDAX and UV-V spectroscopy.
