专利号:WO-2012163976-A1 优先权日:2011-06-03 标题:Continuous process for the synthesis of ternary or quaternary semiconducting nanoparticles based on ib, iiia, via elements of the periodic classification 发明人:RAUSCHER FRANK; FU MIN; MLECZKO LESLAW; HOHEISEL WERNER 权利人:BAYER IP GMBH; RAUSCHER FRANK; FU MIN; MLECZKO LESLAW; HOHEISEL WERNER 摘要:A process for the continuous production of ternary or quaternary semiconducting nanoparticles based on IB, IIIA, VIA elements of the periodic classification, in particular low-toxic AglnS2; and CuInS2 in the liquid phase is described. A uniform size of semiconducting nanoparticles is obtained in a size range from 1 nm to 20 nm, showing chalcopyrite or wurzite crystal structure. The size and crystal structure of the semiconducting nanoparticle can be controlled by adjusting reaction parameters in particular concentration, temperature, flow and selected ligands.
