“…The hydrogen functional group can react with vinyl group in siloxane matrix and oleic acid. [11] It can enhance thermal stability of QD due to its high thermal stability. In addition, siloxane hybrid LED encapsulant much improve the stabilities of QDs compared with previous reported photo SE-QD, which have methacryl functional group with low degradation temperature.…”

“…Polymer-based luminescent films are frequently used in sensors, , solar concentrators, , and light-emitting diodes (LEDs). ,− Fabrication of such composite films often involves two processes: (i) synthesis of the luminescent component, such as an organic dye, semiconductor quantum dots (QDs), or metal nanoclusters (NCs) in solution, and (ii) dispersion of these in a monomer or a dissolved polymer, followed by polymerization/evaporation of the solvent. − However, widespread application of this approach is in part hindered by several limitations: (i) sometimes poor dispersion of luminescent components in the polymer, leading to the phase segregation which makes it difficult to fabricate large-area, uniformly luminescent films; (ii) deterioration of the photoluminescence (PL) quantum yield (QY) of the luminescent component during the fabrication process of the film; (iii) poor PL stability, particularly when the films are exposed to heat, oxygen, or moisture. − …”

Composite polymer films incorporating luminescent copper nanoclusters are conveniently fabricated by solution processing of a precursor mixture of polyvinylpyrrolidone, poly(vinyl alcohol), a Cu2+ salt, and glutathione in water. The formation of Cu nanoclusters takes place through chemical reactions of the precursors in a hydrogel network, whose dehydration during the subsequent aging process leads to aggregation-induced emission enhancement. Large-area (25 cm × 32 cm), flexible, transparent, thermally stable, bright-orange-emitting films are realized, with the photoluminescence quantum yield reaching 30%. The emission of the films is attributed to a phosphorescence mechanism, taking place through ligand-to-metal charge transfer followed by a radiative relaxation over a triplet state. Cu-nanocluster-based composite films are employed as a light-emitting layer for down-conversion orange light-emitting diodes.

Mini/microlight‐emitting diodes (LEDs) are one of the most promising technologies for next‐generation displays to meet the requirements of demanding applications, including augmented reality/virtual reality displays, wearable devices, and microprojectors. To realize full‐color displays, the strategy of combining miniaturized blue nitride‐based LEDs with color conversion layers is promising due to the high efficiencies of the LEDs and the advantageous manufacturing. Quantum dots (QDs), owing to their high photoluminescence quantum yield, small particle size, and solution processability, have emerged as the color conversion material with the most potential for mini/micro‐LEDs. However, the integration of QDs into display technologies poses several challenges. From the material side, the stability of QD materials is still challenging. For the case of packaging QDs in a matrix, the dispersion quality of QDs and the light extraction of the emission need to be improved. From the fabrication side, the lack of high‐precision mass manufacturing strategies in QD pixelation hinders the widespread application of QDs. Toward the issues above, this review summarizes the research on QD materials for color conversion display in recent years to systematically draw an overview of the packaging strategies, the light management approaches, and the pixelation methods of QD materials toward mini/micro‐LED‐based display technologies.
