The Size-Dependent Photonic Characteristics of Colloidal-Quantum-Dot-Enhanced Micro-LEDs
Micromachines, 2023 Colloidal CdSe/ZnS quantum dots (QD) enhanced micro-LEDs with sizes varying from 10 to 100 μm were fabricated and measured. The direct photolithography of quantum-dot-contained photoresists can place this color conversion layer on the top of an InGaN ...

Micro-LED Waveguide for Fluorescence Applications [PDF]
2019 IEEE Photonics Conference (IPC), 2019 A micro-LED-coupled multimode slab waveguide is reported for fluorescence sensing. The device consists of a 1-dimensional micro-LED array coupled to a sub-mm polymeric slab for evanescent excitation of fluorescent analytes present on the surface. Proof-principle detection of semiconductor nanocrystals down to 0.2 pM/cm2 is demonstrated.

Study on the effect of size on InGaN red micro-LEDs [PDF]
Scientific Reports, 2021 AbstractIn this research, five sizes (100 × 100, 75 × 75, 50 × 50, 25 × 25, 10 × 10 µm2) of InGaN red micro-light emitting diode (LED) dies are produced using laser-based direct writing and maskless technology. It is observed that with increasing injection current, the smaller the size of the micro-LED, the more obvious the blue shift of the emission ...

Micro‐LED Technologies and Applications [PDF]
Information Display, 2016 Light‐emitting diodes (LEDs) offer extraordinary luminance, efficiency, and color quality, but to date are largely used in displays as backlights or packaged pixel elements in large‐area LED billboard displays. Building high‐performance emissive displays in a smaller form factor requires a new micro‐LED technology separate from what is used for large ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
