Abstract
A quantum dot substrate, a method for preparing the same, and a display device thereof. The quantum dot substrate includes a quantum dot film. The quantum dot film includes a plurality of quantum dots and a plurality of first nanoparticles dispersed among the plurality of quantum dots. A particle size of the plurality of first nanoparticles ranges from 2 nanometers (nm) to 50 nm. In the present application, a self-absorption phenomenon of the plurality of quantum dots is reduced and luminous efficiency of the plurality of quantum dots is enhanced through arranging the plurality of first nanoparticles with particle sizes ranging from 2 nm to 50 nm among the plurality of quantum dots.
