Kinetic Study of Atmospheric Pressure Nitrogen Plasma Afterglow Using Quantitative Electron Spin Resonance Spectroscopy

Journal of Spectroscopy, 2017
Quantitative electron spin resonance spectroscopy is used to measure nitrogen atom density in atmospheric pressure dielectric barrier discharge afterglow. The experiment shows that oxygen injection into early afterglow increases the nitrogen dissociation

Organic Afterglow Vesicles

Advanced Science, EarlyView.
This work constructs organic afterglow vesicles through polymerization‐induced self‐assembly (PISA), integrating thermally activated delayed fluorescence (TADF) type organic afterglow emitters into block copolymer nanostructures. The resulting vesicles exhibited significant room‐temperature afterglow, with an emission lifetime exceeding 200 ...

Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

Advanced Physics Research, EarlyView.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...

Charge decay in the spatial afterglow of plasmas and its impact on diffusion regimes

Nature Communications, 2023
The spatial afterglow is a region at the boundary of a non-equilibrium plasma where charged species relax into ambient equilibrium. In many applications, the spatial afterglow is the part of the plasma that interacts with surfaces, such as suspended ...

Enabling robust blue circularly polarized organic afterglow through self-confining isolated chiral chromophore

Nature Communications
Creating circularly polarized organic afterglow system with elevated triplet energy levels, suppressed non-radiative transitions, and effective chirality, which are three critical prerequisites for achieving blue circularly polarized afterglow, has posed
