Abstract
Disclosed herein is a nanocrystal-metal oxide complex. The nanocrystal of the nanocrystal-metal oxide complex is substituted with two or more different types of surfactants which are miscible with a metal oxide precursor and enable maintenance of luminescent and electrical properties of the nanocrystal. The nanocrystal-metal oxide complex exhibits superior optical and chemical stability and secures high luminescent efficiency of the nanocrystal. Accordingly, when the nanocrystal-metal oxide complex is used as a luminescent material of an electroluminescent device, it can improve luminescent efficiency and reliability of products. Further disclosed herein is a method for preparing the nanocrystal-metal oxide complex.
