Predictions for The Very Early Afterglow and The Optical Flash

, 1999
According to the internal-external shocks model for $\gamma $-ray bursts (GRBs), the GRB is produced by internal shocks within a relativistic flow while the afterglow is produced by external shocks with the ISM.

Identifying the Location in the Host Galaxy of the Short GRB 111117A with the Chandra Sub-arcsecond Position

, 2013
We present our successful Chandra program designed to identify, with sub-arcsecond accuracy, the X-ray afterglow of the short GRB 111117A, which was discovered by Swift and Fermi.

Persistent Luminescence Analysis in the Frequency Domain

Advanced Optical Materials, EarlyView.
A frequency‐domain framework is introduced to characterize persistent luminescence materials. This method surpasses the limitations of time‐domain techniques and provides a new approach to understanding and optimizing the photophysical behavior of complex luminescent systems involving processes with different temporal dynamics.

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

First Tellurite Composite Fiber with NIR‐Driven Green Persistent Luminescence

Advanced Optical Materials, EarlyView.
The first composite fiber based on SrAl2O4:Eu2+, Dy3+ PeL phosphors embedded in Yb3+/Tm3+ co‐doped tellurite glass is developed. The fiber exhibits green afterglow driven by 980 nm laser injection, suggesting that the PeL phosphors survive the fabrication process and the blue upconversion from the Yb3+/Tm3+ co‐doped glass matrix is strong enough to ...

A generic approach towards afterglow luminescent nanoparticles for ultrasensitive in vivo imaging

Nature Communications, 2019
Afterglow luminescence is used to reduce background noise and increase sensitivity; however, biocompatible afterglow materials are limited. Here, the authors report on an approach to turn standard optical agents into afterglow nanoparticles and ...
