Uniform Transfer of Luminescent Quantum Dots onto a Substrate |
摘要 |
A method of uniformly transferring luminescent quantum dots onto a substrate, comprising: a) preparing a colloidal suspension of luminescent quantum dots in a hydrophobic solvent, wherein the density of the hydrophobic solvent is from 0.67 g/cm3 to 0.96 g/cm3; b) dispensing the suspension onto a convex aqueous surface; c) allowing the hydrophobic solvent to evaporate; d) contacting the film of luminescent quantum dots with a hydrophobic stamp; and e) depositing the film of luminescent quantum dots onto a substrate with the hydrophobic stamp is described herein. Further described is a method of preparing quantum dot based light emitting diodes.
