Abstract

Disclosed are quantum dot solid-state film, method for preparing same, and quantum dot light-emitting diode. Method comprises: providing quantum dot solution, preparing quantum dot material solid-state film on substrate; before being immersed in surface modifier solution to obtain quantum dot material solid-state film modified by a surface modifier; providing a metal nanoparticle seed solution, using solution method to deposit nanoparticle on quantum dot material solid-state film modified by surface modifier to obtain a quantum dot material solid-state film with the surface having adsorbed a layer of metal nanoparticle seed; before being immersed in a metal nano wire precursor solution, nanoparticle to perform a metal nano wire growth, finally obtaining a quantum dot solid-state film. The quantum dot solid-state film obtained using method of invention can effectively and rapidly transmit electrical charges, improving overall performance of device.
