Rigid polymer matrix enables direct red afterglow from rhodamine dyes without energy transfer

FlexMat, EarlyView.
This work presents a universal and facile strategy to achieve direct red room‐temperature phosphorescence from commercial rhodamine dyes by harnessing the superior rigid confinement of a novel phosphorus‐containing polymer (DOBP), effectively bypassing the complex TS‐FRET process.

Decay of metastable atoms in the afterglow of single-electrode breakdown

Physics of Complex Systems
This paper deals with experimental studies of ionization waves igniting the breakdown in long discharge tubes in neon at low pressures. Ionization waves were produced by rectangular voltage pulses applied to the high-voltage electrode of the discharge ...

On-axis orphan afterglows

New Astronomy, 2003
In many GRB inner engine models the highly relativistic GRB jets are engulfed by slower moving matter. This could result in different beaming for the prompt $γ$-ray emission and for the lower energy afterglow. In this case we should expect that some observer will see {\it on-axis orphan afterglows}: X-ray, optical and radio afterglows within the ...

NTECARS: A Nonthermal Equilibrium CARS Spectra Fitting Code

Journal of Raman Spectroscopy, EarlyView.
We present NTECARS, an open‐source code written in Julia for the calculation and fitting of CARS spectra under nonequilibrium conditions. Rovibrational distributions can be flexibly modeled and fitted for different use cases. The code currently implements CO2$$ \mathrm{C}{\mathrm{O}}_2 $$ and N2$$ {\mathrm{N}}_2 $$ molecules and is validated under ...

Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics

Laser &Photonics Reviews, EarlyView.
This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...
