Stable P‐Type PbS Quantum Dot Ink for all‐Blade‐Coated Short‐Wavelength Infrared Photodiodes
Advanced Materials, EarlyView.Stabilization of p‐type PbS quantum dot ink is achieved through hydrogen bonding between fluorinated alcohols solvent and the MP ligand, allowing a six‐day shelf‐life. The solvent does not compromise pre‐deposited layers, enabling fully blade‐coated photodiodes in both n–p and p–n architectures, with enhanced detectivity and bandwidth compared to layer‐

Nippon Laser Igakkaishi, 2019 The possibility of using photoacoustic imaging for functional diagnosis has attracted much attention especially in the clinical field. Among such imaging systems, a system, which offers real-time imaging using compact and low-priced LEDs as a light source, has appeared. Compared to solid state lasers, the LED pulse energy was extremely small, so it had
