The present invention relates to a method for preparing a quantum dot-inorganic matrix composite, which comprises preparing an inorganic matrix precursor solution including a precursor of quantum dots, and rotating coating and heat treatment on a substrate to obtain a quantum dot-inorganic matrix composite. The quantum dot-inorganic matrix composite prepared by is filled with high-density quantum dots in an inorganic matrix with high density, and has excellent luminous efficiency, and can be easily manufactured by low temperature process, which can be usefully applied to various displays and electronic devices. Can be. |
