Controllable Fabrication of Organic Semiconductors for Aligned Microlasers and Integrated Photodetectors

Engineering of organic semiconductors toward oriented array structures contributes to integrated optoelectronics and organic lasers. Template-confined method provides an efficient way for the fabrication of long continuous microribbon array, which can be devided into specific subunits by femtosecond laser processing technique. The prepared microribbon...

Triggering Long Persistent Luminescence From Functionalizable Carbon Dots‐in‐Carbon Nitrides Composites Via Production of Deep‐Traps

A new type of color-tunable metal-free long persistent luminescent (LPL) materials (named CDs@CNs) with outstanding functionalization capability are prepared via in situ embedding of carbon dots (CDs) into carbon nitrides (CNs). The formation of deep traps and covalent fixation of CDs are key to the ultra-long (up to 10 min) and robust LPL. The surface...

Coherent‐Resonance Enhancement of Sensing at the Exceptional Points

A coherent-resonance exceptional point (EP) sensor is demonstrated theoretically and experimentally by introducing coherent resonance between the whispering gallery microcavity and two external sub-wavelength resonators. Compared to previous noncoherent EP sensors, this system significantly improves the sensitivity without increasing the order of...

Ultrafast Quasi‐2D/3D Perovskite Photodetectors Conferred Using Interfacial Engineering of Self‐Assembled Monolayers

A series of silane-coupling agents are applied on the silicon wafer surface to modify the morphology and photodetector performance of quasi-2D CsPbBr3 films. The photodetector on the (3-chloropropyl)trichlorosilane-modified surface shows larger crystallite size, prolonged exciton lifetime, and better stability than that on the pristine surface. This...

TADF Regulation by Tuning Keto‐Energy Levels, ISC/RISC Equilibrium in Coordination Polymers with Excited State Intramolecular Proton Transfer (ESIPT)

A new tactic is applied for the regulation of keto-energy levels and intersystem crossing or reverse intersystem crossing (ISC)/(RISC) equilibrium via the introduction of electron-withdrawing fluorine in a series of excited state intramolecular proton transfer (ESIPT) ligands and corresponding Cd(II) coordination polymers. Abstract Thermally...

High‐Throughput Fabrication of Phosphor‐In‐Silica Glass via Injection Molding

Different kinds of phosphor-in-silica glass (PiSG) are fabricated with high productivity using the classical injection molding technique. The as-fabricated samples can be produced with different shapes and within short time. The as-fabricated PiSG possesses excellent optical properties and high chemical and thermal stabilities, making them promising...
