ABSTRACTThe controlled hydrolysis of Al(O-sec-Bu)3 and Y(O-iso-Pr)3 or the reaction of Y(OOCCH)3 with partially hydrolyzed Al(O-sec-Bu)3 [AlO0.75(O-sec-Bu)1.5] resulted in the formation of soluble polymeric materials. Pyrolysis of these materials under a flow of oxygen led to the formation of yttrium aluminum garnet (YAG) at 650-1500°C. YAG was the only crystalline phase observed during pyrolysis, and the Al/Y ratio of the pyrolysis products and the starting material was identical. However, infrared spectroscopy indicated that carbonate groups and entrained CO2 existed in the products at temperatures up to 1250°C. The pyrolysis chemistry of the precursors and the microstructure of the products were studied by FT-IR, TGA, XRD, SEM and elemental analyses.

The growth and characterization of europium ( Eu 3+) and terbium ( Tb 3+) doped yttrium aluminum garnet ( Y 3 Al 5 O 12 or YAG) and undoped ZnGa 2O4 photoluminescent thin films deposited on sapphire substrates at 400°C by excimer pulsed laser ablation is reported. Smooth, continuous 500-nm-thick amorphous films were produced with compositions depleted in oxygen. Luminescence measurements on the as-deposited and on annealed samples revealed that heat treatments at temperatures > 800°C were necessary to induce crystallization and reoxygenate, which coincided with the onset of luminescence. Annealing produced randomly oriented grains on the order of 15-200 nm.
