Abstract
A quantum dot, a color conversion panel, and a display device, the quantum dot including a core; and a shell layer positioned outside of the core, wherein at least one of the core and the shell layer is doped with aluminum, silicon, titanium, magnesium, or zinc, and the core includes a Group III-V compound.
Claims13
A color conversion panel, comprising:
- a substrate;
- a first color conversion layer and a second color conversion layer positioned on the substrate;
- and
- a planarization layer covering the first color conversion layer and the second color conversion layer, wherein:
- each of the first color conversion layer and the second color conversion layer includes a plurality of semiconductor nanoparticles,
- each semiconductor nanoparticle of the plurality of semiconductor nanoparticles includes a core and a shell layer positioned outside of the core, the shell layer comprising a first portion and a second portion, the second portion being farther from the core than the first portion, and
- the second portion of the shell layer is doped with aluminum oxide, silicon oxide, titanium oxide, magnesium oxide, or zinc oxide to have a different composition than the first portion.
