Description

Inorganic nano material prints ink and its preparation method and application

Technical field

The invention belongs to electroluminescent diode field of display technology more particularly to a kind of inorganic nano material to print ink And preparation method thereof.

Background technique

Quantum dot (quantum dot, QD), but can be described as it is nanocrystalline, be one kind by II-VI group or iii-v element The nano particle of composition.Quantum dot is the nano semiconductor material of zero dimension (zero-dimensional), the ruler of three of them dimension Twice of the very little exciton Bohr radius for being all not more than its corresponding semiconductor material, the performance of quantum dot is generally imitated by quantum confinement Answer the influence of (quantum confinement effect), skin effect and doping.The partial size of quantum dot is typically in the range of 1~ Between 10nm, since electrons and holes are by quantum confinement, continuous band structure becomes the discrete energy levels knot with molecular characterization Structure can emit fluorescence after being excited.Quantum dot has the performances such as novel electronics and optics, and the chemical component of quantum dot ensures Luminescent color can cover the entire visual field from blue light to feux rouges, and excitation purity is high, continuously adjustable, is to have breakthrough work The material of industry application.In recent years, quantum dot light emitting material is playing very big effect in fields such as LED illumination, liquid crystal displays, Quantum dot substitutes traditional fluorescent powder, effectively improves the colour gamut of LED and liquid crystal display.Recently, luminescent material is as hair The light emitting diode with quantum dots (QLED) of photosphere is with a wide range of applications in fields such as solid-state lighting, FPD, by The extensive concern of academia and industrial circle.

The solution processing properties of quantum dot allow quantum dot light emitting layer to pass through spin coating, blade coating, injection, inkjet printing etc. Various ways preparation.Opposite front several method, inkjet printing technology can be accurately in the desired amount by quantum dot light emitting material Deposit it is in place, allow semiconductor material uniform deposition formed film layer.Quantum dot light emitting layer, material are prepared by inkjet printing The utilization rate of material is very high, and manufacturer can reduce production cost, simplifies manufacture craft, is easy universal volume production, reduces cost.Spray Black printing technique is the effective ways of the manufacture problem that can solve large scale QLED screen generally acknowledged at present.

However, inkjet printing technology needs to prepare suitable ink, ink needs sufficiently stable.Firstly, ink-jet print Water needs enough dispersibilities and hydrophobicity, nanoparticle is uniformly dispersed under solution state, while avoiding solvent Hydrone is absorbed, the ligand environment of quantum dot surface is destroyed.Secondly, ink-jet printing ink also needs to have viscosity appropriate, table Face tension.Suitable viscosity and surface tension not only may be implemented printer and stablize ink-jet, it is also possible that ink is in pixel square Stabilization is sprawled in battle array, is improved wetability, is effectively prevent excessive and avoid sprawling not in place.Meanwhile suitable viscosity and surface Tension can also realize that solvent is uniformly spread in ink curing processes, prevent from forming the non-uniform ink droplet film such as coffee ring.And For quantum dot ink, there is an urgent need to research and develop one kind to have preferably dispersibility and hydrophobicity, and have controllable viscous Degree, surface tension, and the solvent of removal can be facilitated in last handling process, it is wanted so that quantum dot ink can satisfy inkjet printing It asks, stablizes out of ink, high wettability, stabilization is sprawled, and uniform drying forms a film uniform.
