Abstract
A film, a preparation method thereof and a photoelectric device are disclosed. The film includes a cross-linked system with voids and a nanoparticle filled in the voids. Compared with a cross-linked system without ions, the cross-linked system of the present disclosure contains cations and anions, so that the cross-linked system itself has good conductivity, which is conducive to the recombination of electrons and holes in the film, thereby making the film have good luminescent performance.
