Abstract

The application provides an ink composition which comprises nano-granules and a sublimable compound. The ink composition provided by the application contains the sublimable compound, and after removing the sublimable compound, a nano-granular film can be directly obtained so as to avoid the coffee-ring effect of the ink composition in the drying process.

Description

technical field [0001] The application belongs to the field of nanotechnology, and in particular relates to an ink composition, a nanoparticle film and an optoelectronic device. Background technique [0002] Nanoparticles have great application prospects in optoelectronic devices, such as CdSe nanoparticles, CdS nanoparticles, InP nanoparticles, etc. are widely used as light-emitting materials for electroluminescent devices, such as ZnO nanoparticles, MgO nanoparticles, NiO nanoparticles etc. are widely used as carrier transport materials in electroluminescent devices and photovoltaic devices. [0003] A common method for preparing a nanoparticle film is to deposit an ink composition containing nanoparticles on a substrate by inkjet printing and then dry it. However, when the ink composition dries, the nanoparticles tend to deposit as rings at the ink droplet edges, resulting in a pronounced coffee ring phenomenon. Contents of the invention [0004] In view of the above-...
