Aggregation-Induced Emission: Together We Shine, United We Soar!

Luminogenic materials with aggregation-induced emission (AIE) attributes have attracted much interest since the debut of the AIE concept in 2001. In this critical review, recent progress in the area of AIE research is summarized. Typical examples of AIE systems are discussed, from which their structure–property relationships are derived. Through mechanistic decipherment of the photophysical processes, structural design strategies for generating new AIE luminogens are developed. Technological, especially optoelectronic and biological, applications of the AIE systems are exemplified to illustrate how the novel AIE effect can be utilized for high-tech innovations (183 references).

Aggregation-induced emission

"United we stand, divided we fall."--Aesop. Aggregation-induced emission (AIE) refers to a photophysical phenomenon shown by a group of luminogenic materials that are non-emissive when they are dissolved in good solvents as molecules but become highly luminescent when they are clustered in poor solvents or solid state as aggregates. In this Review we summarize the recent progresses made in the area of AIE research. We conduct mechanistic analyses of the AIE processes, unify the restriction of intramolecular motions (RIM) as the main cause for the AIE effects, and derive RIM-based molecular engineering strategies for the design of new AIE luminogens (AIEgens). Typical examples of the newly developed AIEgens and their high-tech applications as optoelectronic materials, chemical sensors and biomedical probes are presented and discussed.

Photolithography is a high resolution and mature patterning technique which has been widely used in semiconductor industry. For display application, a pixel consists of red (R), green (G) and blue (B) side-by-side sub-pixels, which thereby requires a high resolution patterning of the light-emission layers. In this work, photolithography is used to fine pattern the quantum dot (QD) light-emitting layers. To prevent the QDs being washed off during the lift-off process, the ZnMgO layer is treated by the hydrophobic material hexamethyldisilazane (HMDS). With HMDS treatment, the adhesion between the QDs and the ZnMgO is effectively improved. As a result, side-by-side RGB QD with pixel size 30 μm × 120 μm is successfully achieved. After patterning, the R, G and B QLEDs exhibit a maximum current efficiency of 11.6 cd/A, 29.7 cd/A and 1.5 cd/A, respectively. Author

We report a FA and MA mixed hybrid perovskite quantum dot light emitting diodes using a simple synthesis method at room temperature. The green light-emitting diodes used FA x MA 1−x PbBr 3 quantum dots as emitting layer, which exhibited maximum luminence of 6000 cd/A, current efficiency of 6 cd/A and external quantum efficiency of 3.5%, which is more efficient than the pure FAPbBr 3 PeLED. This provides an alternative route toward high efficient solution-processed perovskite-based light-emitting diodes.

Efficient perovskite light-emitting diodes based on double organic cations

Quantum-dot light-emitting diodes (QLEDs) has been regarded as the promising candidate for next generation displays by lots of researchers, because they possess many merits such as high color purity, wide color gamut, simple and low-cost solution processability. [1-3] Top (T) emission (E) QLEDs has always been the focus of quantum dot diode research, because it can well combined with the drive circuit, emitting light away from the substrate and the backplane electric circuit, which increases the aperture ratio of the active matrix flat panel display. To date, among the reported TEQLEDs there still exist some challenge such as low efficiency and view angle dependence which is very unfavorable for the panel display. [4-6] Here, by introducing a transparent nanosphere scattering layer covering on the transparent conductive top electrode, we demonstrate highly efficient TEQLEDs which simultaneously improve the outcoupling efficiency and eliminate viewing angle dependence. Through further optimizing of the microcavity of the device, the record external quantum efficiency (EQE) of 32.5% for the red TEQLEDs can be obtained. Furthermore, owing to the scattering effect of nanosphere, the device exhibit no spectral difference as the view angle vary from 0 o (perpendicular to the substrate plane)-75 o . As in this kind of outcoupling strategy are very effective and can be refer as internal coupling, as the top electrode, which is made of transparent conductive materials(IZO), is directly covered with close aligned nanosphere on top, acting as scattering layer. Thus the total reflection at the interface between IZO and air can be greatly reduced. there glass substrate at the light emitting TEQLED waveguide mode IZO and the air
