“…While maintaining the porous nanofiber morphology of ultralight carbon nanotubes, QDs were uniformly distributed along the surface of the carbon nanotube fibers without aggregation and achieved a PLQY of 35%. [77] BC with its nanofiber network structure is a suitable matrix for dispersing QD materials to overcome the fluorescence quenching effect of QD/polymer composites. The obtained quantum yield value with BC matrix is higher than the aerogel-encapsulated ZnS(CuInS 2 )/ZnS QDs, which exhibited a maximal PLQY of 30%.…”

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.

“…Due to its availability, biodegradability, non-toxicity, hydrophilic nature, inexpensive cost, and multifunctionality, cellulose is attractive and shows promise for utilization in sustainable material engineering. The processibility of cellulose allows it to be formed into various types of materials, for example, into hydrogels [17] and/or applied in its dry form as aerogels [18]. Cellulose hydrogels (jelly-like solids) are obtained by the regeneration or crosslinking of cellulose in solutions into a 3D shape, which are different from the non-cross-linked gel-like suspension of nano-or micro-fibrillated cellulose [19][20][21].…”

This review summarizes the recent advances in preparing cellulose hydrogels via ionic liquid-based processes and the applications of regenerated cellulose hydrogels/iongels in electrochemical materials, separation membranes, and 3D printing bioinks. Cellulose is the most abundant natural polymer, which has attracted great attention due to the demand for eco-friendly and sustainable materials. The sustainability of cellulose products also depends on the selection of the dissolution solvent. The current state of knowledge in cellulose preparation, performed by directly dissolving in ionic liquids and then regenerating in antisolvents, as described in this review, provides innovative ideas from the new findings presented in recent research papers and with the perspective of the current challenges.

“…In recent years, fluorescent aerogel has budded in solid-state lighting and intelligent sensors due to their special optical properties. [22][23][24][25][26][27] Further using an aerogel as a structure template, doping small fluorescent molecules into 3D structure with low density and high porosity is an effective way to prepare some fascinating WLE materials. [28][29][30][31][32] As an emerging member of these aerogels, the fluorescent nanofiber aerogel (NFA) has a 3D network which is conducive for the uniform dispersion of fluorescent molecules.…”

White light could be achieved by controlling the energy transfer (ET) of different fluorescent molecules in the donor-acceptor system. However, it is still a huge challenge to inhibit the excessive ET efficiency and achieve a wide range of white-light-emitting (WLE) spectrum. In this study, the authors develop a simple and efficient method to prepare a fluorescent nanofiber aerogel (NFA). The 3D nanofiber network is conducive to the uniform dispersion of fluorescent molecules and can effectively inhibit the excessive ET between donor and acceptor. By simply adjusting the mass ratios of blue and orange fluorescent nanofibers in the NFA to 3:2, a uniform white light (0.322,0.305) that covered the entire visible region is obtained. This WLE-NFA has an ultra-light volume density of 6.47 mg cm -3 and its quantum yield is up to 27%. In addition, the fluorescent NFA can also be processed into different 3D shapes and integrated luminous patterns through various designs of the freezing mold. This brand-new fluorescent NFA can overcome the poor plasticity of traditional fluorescent nanofiber films, which is expected to provide a new thought for developing next-generation flexible WLE materials.
