Self‐Sterilizing Face Mask Employing Enzymatic Power Generation

Advanced Materials Technologies, EarlyView.
Electric face mask with flexible biofuel cell integration for on‐the‐go sterilization is developed utilizing ethanol oxidation via alcohol dehydrogenase, and oxygen reduction via bilirubin oxidase. Modified face mask exhibited bacterial death rates of 40–60% at only 20 µA of electric current, easily generated by the biofuel cell continuously over hours

Tunable‐Wavelength Broadband Liquid‐State Carbon‐Quantum‐Dot Lasers

Advanced Optical Materials, EarlyView.
This work provides a gain‐induced waveguide structure to achieve programmable mode spacing by coupling liquid‐state lasing of carbon quantum dots to a vertically placed aluminum mirror, enabling an unprecedented transition from random lasing to multimode lasing without cumbersome micromanufacturing, even single‐mode lasing at a wide range from 641 to ...

Understanding the Role of Fabry‐Perot Resonances in Maximizing Absorption for Ultrathin Sn Halide Perovskite Optoelectronic Devices

Advanced Optical Materials, EarlyView.
A design principle is presented that maximizes absorption in ultrathin (tens of nanometers) Sn halide perovskite optoelectronic devices by aligning their intrinsic absorption wavelengths with Fabry–Pérot (FP) resonances. The ultrathin FASnI3 devices exhibit increases open‐circuit voltage, reduces dark current, and high photocurrent, yielding high ...

Enhanced Stability of Cd‐Free Quantum Dot Light‐Emitting Diodes via Yttrium Acetate‐Modified ZnMgO: Suppressing Mg Migration

Advanced Optical Materials, EarlyView.
A surface passivation strategy using yttrium acetate to suppress Mg ion migration from the ZnMgO electron transport layer is proposed. This treatment restores oxygen vacancies on the ZnMgO surface, enhancing device stability. The Cd‐free quantum dot light‐emitting diodes demonstrate a 65.5% increase in operational lifetime with an external quantum ...

Enhanced Amplified Spontaneous Emission from Optically Pumped Perovskite Light‐Emitting Diodes with Sodium Fluoride Additives

Advanced Photonics Research, EarlyView.
This study investigates sodium fluoride (NaF) as an additive in halide perovskite films to improve their optical and light amplification properties for application in laser diodes. The incorporation of NaF leads to a threefold increase in light‐emitting intensity and a 20% reduction in the amplified spontaneous emission (ASE) threshold, along with ...
