TECHNOLOGY FOCUS - IMAGING AND COMMUNICATION - Preferred Process: In the process (p1), the ratio of sum of boron, aluminum and indium to zinc in the ink is 0.02-10; the heating is at a temperature of 50-500 degrees C; the heating is performed in air having controlled humidity; the ink further comprises at least one dopant element comprising halides, magnesium, yttrium, titanium, zirconium, niobium, chromium, ruthenium, bismuth, antimony or lanthanum; the depositing is done with an 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; and the substrate is a glass, a ceramic, or a polymer.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preparation: No preparation method is given. Preferred Components: (I) are: materials containing aluminum, boron, indium, zinc and oxygen, when each of a and d is at least 0.01; materials containing aluminum, indium, zinc and oxygen, when d is 0; materials containing boron, indium, zinc and oxygen, when a is 0. EXAMPLE - To a 200 ml round bottom flask, 0.236 g tris(2-tert-Butoxy-1-methyl-ethoxy) aluminum, 0.284 g tris(2-tert-butoxy-1-methyl-ethoxy) indium, 0.155 g bis(2-isopropoxy-ethoxy) zinc and 40 ml benzene were added. The reaction mixture was magnetically stirred and heated at 45 degrees C (oil bath) for 15 minutes, resulting in formation of a colorless solution. Stirring was continued for 16 hours at 23 degrees C (room temperature) followed by filtration through a glass fiber pad. Subsequent removal of the volatile species under reduced pressure at 23 degrees C and heating of the residue at 70 degrees C for 1 hour afforded 0.42 g to obtain precursor compound containing aluminum, indium, zinc and oxygen (aluminum0.99-indium0.98-zinc(2-tert-butoxy-1-methyl-ethoxy)5.91(2-isopropoxy-ethoxy)2).
