Abstract
Official abstract text for this publication.
The present invention relates to a phosphine precursor for the preparation of a quantum dot, and a quantum dot prepared therefrom. Using the phosphine precursor for the preparation of a quantum dot of the present invention, a quantum dot with improved luminous efficiency and higher luminous color purity can be provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A phosphine precursor composition for preparation of a quantum dot, comprising a phosphine precursor selected from the group consisting of the following Structural Formulas, and tris(trimethylsilyl)phosphine at a mole ratio of 1:1: 2. A method for preparing the phosphine precursor of claim 1 , comprising the steps of: preparing a mixture of a silyl triflate compound, halogenated hydrocarbon, and tertiary amine; and adding phosphine to the mixture. 3. A method for preparing the phosphine precursor of claim 1 , comprising the steps of: preparing a mixture of a primary phosphine compound, halogenated hydrocarbon, and tertiary amine; and adding a silyl triflate compound to the mixture. 4. The method for preparing the phosphine precursor according to claim 2 , wherein the halogenated hydrocarbon is dichloromethane, and the tertiary amine is trimethylamine.
