Highly crystalline, phase- and size-controlled CoO nanocrystals of hexagonal and cubic phases have been prepared by thermal decomposition of Co(acac)3 in oleylamine under an inert atmosphere. Kinetic and thermodynamic control for the precursor formation leads to two different seeds of hexagonal and cubic phases at higher temperatures. The crystal size of both CoO phases can be easily manipulated by changing the precursor concentration and reaction temperature.
通过在惰性气氛下，在油胺中热分解Co(acac)3，制备出了具有高度结晶性、相和尺寸可控的六方相和立方相CoO纳米晶体。前驱体形成过程中的动力学和热力学控制在较高温度下产生了六方相和立方相两种不同的晶种。通过改变前驱体浓度和反应温度，可以轻松控制两种CoO相的晶体尺寸。
