This invention relates to optoelectronic devices, namely, to optoelectronic devices based on organic light-emitting diodes, which include the active electroluminescent layer containing quantum dots with the modified surface. Active electroluminescent layer of optoelectronic device includes the first organic hole transport layer soluble in a nonpolar solvent, second organic electron transport layer soluble in a nonpolar solvent, between which the layer of semiconductor quantum dots is located, deposited from a solution in the polar solvent. The surface of quantum dots was preliminarily modified by amphiphilic conductive polymer, at that the surface of semiconductor quantum dots prior to modification was hydrophobic and contained over its entire area a layer of the surfactant, which thickness was from 0.7 nm to 3 nm. |
