Abstract Quantum dots (QDs) are essential luminescent materials with applications in wide‐color‐gamut displays requiring exceptional color reproducibility. Multinary semiconductor QDs composed of groups I, III and VI elements are expected to serv

Silver indium sulfide (AIS)/gallium sulfide (Ga–S) core/shell QDs exhibit a narrow band-edge photoluminescence (PL) in the yellow color region, and shifting the PL wavelength is crucial for optical applications. In this study, we attempt to redshif

Here, silver indium sulfide (AgInS2/gallium selenide core/shell quantum dots (QDs) were developed to exhibit red band-edge emission. Previously, we developed AgInS2/gallium sulfide core/shell QDs, which exhibited yellow band-edge photoluminescence (P

Narrowing the emission peak width and adjusting the peak position play a key role in the chromaticity and color accuracy of display devices with the use of quantum dot light-emitting diodes (QD-LEDs). In this study, we developed multinary Cu–In–G

The photoluminescence properties of Ag(InxGa1−x)S2 quaternary semiconductor quantum dots are improved by ligand exchange with L-, X-, and Z-type ligands. Analyses of both the quantum dots and byproducts are performed for understanding the mechanism
