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

open access: yesAdvanced 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 ...

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...

Modulating Signal Generation in Aptamer‐Based CNT‐FET Biosensors by Controlling the Functionalization Route

open access: yesAdvanced Sensor Research, EarlyView.
The impact of different assembly strategies is discussed on the performance of nanoscale aptamer‐based SWCNT‐FET biosensors. By combining electrical and optical characterization, this is revealed that how aptamer conformation affects local electrostatic changes within the Debye length, leading to distinct sensor responses.

Dual Charge Transfer Mechanisms in Intimately Bonded S‐scheme Heterojunction Photocatalyst with Expeditious Activity toward Environmental Remediation

open access: yesAdvanced Sustainable Systems, EarlyView.
A novel MBOdCN S‐scheme heterojunction photocatalyst is fabricated using pristine Mg‐Bi2O3 and grayish g‐C3N4, where dynamic dual charge migration paths occur to accelerate exciton dissociation. This composite catalyst realizes high degradation efficiency of up to 99.56% of oxytetracycline (OTC) removal under optimized conditions. The material exhibits

Sustainable Flame‐Retardant Poly Lactic Acid Biocomposites Reinforced with Polyphosphate‐Enriched Microalgae: Unlocking the Potential of Hyper‐Compensation

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores microalgae cultivation for wastewater treatment and enhancement of poly lactic acid (PLA)‐based biocomposites. It achieves up to 99.9% nutrient removal, increases biomass productivity by 322%, and demonstrates a triphasic luxury phosphorus uptake system. Incorporation into PLA improves fire‐retardant properties, suggesting potential
