TECHNOLOGY FOCUS - IMAGING AND COMMUNICATION - Preferred Components: The ink further comprises at least one dopant element comprising halides, magnesium, yttrium, titanium, zirconium, niobium, chromium, rubidium, bismuth, antimony or lanthanum. The ratio of (indium and gallium) to zinc in the ink is 0.02-10. The substrate is a glass, a ceramic, or a polymer. Preferred Method: The heating is performed at a temperature of 50-500 degrees C in air having controlled humidity. The depositing is done with ink by printing, inkjet printing, aerosol jet printing, gravure printing, reverse gravure printing, reverse offset gravure printing, stamp printing, transfer printing, pad printing, spray pattern printing, flexographic printing, contact printing, reverse printing, thermal printing, lithography, electrophotographic printing, screen printing, spraying, spray coating, spray deposition, spray pyrolysis, coating, dip coating, wet coating, spin coating, knife coating, roller coating, rod coating, slot die coating, meyer bar coating, lip direct coating, capillary coating, liquid deposition, solution deposition, layer-by-layer deposition, spin casting, or solution casting.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No preparation method is given. Preferred Definitions:    R = ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, t-butyl, isopentyl, 2-methylbutyl, 3-methylbutyl, 2,2-dimethylbutyl, 2,3-dimethylbutyl, 2-methylpentyl, 3-methylpentyl, or 4-methylpentyl.    EXAMPLE - To a magnetically stirring mixture of 1.02 g zinc polyalkyl ether of formula (Zn (OCH2CH2OCH(CH3)2)2)n, 1.4 g tris(2-isopropoxy-ethoxy) gallium, and 1.61 g tris(2-isopropoxy-ethoxy) indium in 40 ml toluene at 23 degrees C (room temperature) was added 7 ml 2-isopropoxy-ethanol via syringe over 5 minutes. The reaction mixture was heated at 60 degrees C (oil bath) for 5 hours with continuous stirring, resulting in formation of a colorless solution. The volatile species were then removed at 23 degrees C (room temperature) under reduced pressure. The resulting residue was heated at 50 degrees C under reduced pressure for 2 hours and isolated to afford a colorless solid (octakis(2-isopropoxy-ethoxy)-indium-gallium-zinc oxide) (4 g, yield 99%).
