Title:
METHOD FOR FORMING QUANTUM DOT LAYER, QUANTUM DOT LAYER, OPTICAL ELEMENT, AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/067691
Kind Code:
A1
Abstract:
This method for forming a quantum dot layer (8) containing at least one quantum dot (14) and a metal sulfide (16) comprises: a step for preparing a quantum dot dispersion in which quantum dots are dispersed in a solution containing a precursor of the metal sulfide and halide ions; and a step for applying the quantum dot dispersion to a substrate.
