Abstract

The invention discloses a cross-linked nanoparticle film and amanufacturing method thereof, and a thin film optoelectronic device. The method comprises the following steps of dispersing nanoparticlesin a solvent, stirring uniformly and acquiring a nanoparticle solution; and through a solution method, manufacturing the nanoparticle solution into a nanoparticle film, injecting a combined gas to urge cross-linked reaction generation, and acquiring the cross-linked nanoparticle film. In the invention, when the nanoparticles form a film, the combined gas is injected so that the particles are urgedto carry out mutual crosslinking. Therefore, the electrical coupling among the particles is increased, the barrier of carrier transmission is reduced, a carrier mobility is increased, and electric performance is greatly improved.

Description

technical field [0001] The invention relates to the field of device thin film preparation, in particular to a cross-linked nanoparticle thin film, a preparation method and a thin film optoelectronic device. Background technique [0002] Oxide nanoparticles (or spherical oxide nanocrystals) have a good degree of crystallinity, which ensures their optical and electrical properties similar to those of bulk materials (low-dimensional materials); on the other hand, due to the self-assembly of nanoparticles into films Very well, so that a low-cost coating preparation process can be applied. In the process of optoelectronic devices prepared by solution method, nanoparticles are one of the important solutions to form the corresponding oxide thin films. Common examples include zinc oxide (ZnO x ) nanoparticles, titanium oxide (TiO x ) Thin films of particles are used as semiconductor materials for transporting electrons in light-emitting diodes, thin-film solar cells, and thin-fil...
