查询词典 pre-prepare

The invention discloses an InP quantum point preparing method, comprising the steps of:(1) mixing InCl3 with trioctylphosphine oxide, and preserving heat at 90-110DEG C to prepare a solution whose In content is 0.1-0.3mol/L;(2) raising temperature to 130-180DEG C, and charging argon gas;(3) injecting PSi(CH333 into InCl3-TOPO compound in the molar ratio of 1 to 1-1 to 2;(4) when the solution color turns into transparent red or orange, raising temperature to 260-270DEG C and preserving heat;(5) lowering temperature to 90-110DEG C and injecting dodecyl amine, decyl amine or mercaptan;(6) dissolving reacting mixture in nonpolar solvent to form transparent colloidal solution, then adding in polar solution until the colloidal solution is muddy, and centrifugally separating and obtaining deposits and supernatant; and (7) centrifugally separating the supernatant, where the above steps (1)-(5) are performed.

本发明公开了一种InP量子点的制备方法，其步骤为：①将InCl 3 与三辛基氧膦混合，在90～110℃保温制得In含量为0.1～0.3mol/L的溶液；②升温到130～180℃，通入氩气；③将PSi(CH 3 3 3 注射入InCl 3 -TOPO复合物中，其摩尔比为1∶1～1∶2；④待溶液颜色变为透明的红色或橙红色，将升温260～270℃保温；⑤降温到90～110℃，注入十二胺、癸胺或硫醇；⑥将反应混合物溶于非极性溶剂，形成透明的胶体溶液，然后加入极性溶剂，直至胶体溶液出现混浊状，然后离心分离获得沉积物和上层清液；⑦取上层清液进行离心分离。上述步骤①～⑤在保护气氛下进行。
