本发明涉及一种钙钛矿型复合氧化物纳米晶体胶的制备方法，该钙钛矿型复合氧化物纳米晶体胶用下述通式(a)表示：Ba1‑xMxTi1‑yNyO3+z(a)；通式(a)中，0≤x＜1，0≤y＜1，z为氧过剩部分；M为碱土金属元素、稀土元素、VIIB族元素、VIII族元素中的至少一种；N为IVB族元素、VIIB族元素、VIII族元素中的至少一种；通式(a)表示的纳米晶体胶的制备方法是将各种金属的有机源溶解在醇溶剂中形成透明溶液，在近室温和静态的条件下，采用自聚集技术合成了各种钙钛矿型复合氧化物。本制备方法合成的纳米颗粒具有优异的单分散性，无需借助表面配体，即可分散至极性溶剂中形成高稳定的纳米胶体溶液。

The invention relates to a preparation method for perovskite type composite oxide nanocrystalline colloid. The perovskite type composite oxide nanocrystalline colloid is expressed as a general formula (a) of Ba(1-x)MxTi(1-y)NyO(3+z), wherein in the general formula (a), x is equal to or larger than 0 and smaller than 1, y is equal to or larger than 0 and smaller than 1, z is an oxygen surplus part, M is selected from at least one of alkaline earth metal, a rare earth element, a VIIB element and a VIII element, and N is selected from at least one of an IVB element, a VIIB element and a VIII element; the preparation method for the nanocrystalline colloid expressed in the general formula (a) comprises the following steps: dissolving organic sources of various metals in an alcohol solvent to form a transparent solution, and under the conditions of near room temperature and static state, adopting a self-aggregation technology to synthetize various perovskite type composite oxides. A nanoparticle, synthetized according to the preparation method, is excellent in monodispersity, and can disperse in a polar solvent to form a high-stability nano-sized colloidal solution, without a surface ligand.
