Enhanced Near-Infrared-Excitable Organic Afterglow Nanoparticles for Deep-Tissue Multimodal Imaging via Singlet Oxygen-Mediated Energy Transfer [PDF]
ResearchAfterglow imaging offers exceptional signal-to-background ratios (SBRs) by circumventing real-time excitation and autofluorescence, yet conventional systems rely on visible-light excitation, limiting tissue penetration and signal intensity.

Temporal dusty plasma afterglow: A review
Frontiers in Physics, 2022 In complex plasmas, dust particles are charged through their interactions with the electrons and ions of the surrounding plasma. In low-temperature laboratory plasmas, dust particles most commonly acquire a negative charge. In particular, in a laboratory

Astronomy and Astrophysics Supplement Series, 1999 We calculate the expected spectrum and light curves of the early afterglow. For short GRBs the peak of the afterglow will be delayed, typically, by a few dozens of seconds after the burst. The x-ray and gamma-ray characteristics of this delayed emission provide a way to discriminate between late internal shocks emission (part of the GRB) and the early ...

Green Afterglow of Undoped SrAl2O4
Nanomaterials, 2021 Undoped SrAl2O4 nanocrystals were obtained via solution combustion using urea as fuel. The afterglow properties of undoped SrAl2O4 were investigated. Green afterglow from undoped SrAl2O4 is visible to the human eye when the 325 nm irradiation of a helium–

UnderCurrents: Journal of Critical Environmental Studies, 2022 You can see Afterglow in motion at https://tiny.cc/uc_afterglow or https://youtu.be/kjKQr38c7qA.This mixed media piece explores the relationship between memory and home videos. The chosen scene is an everyday glimpse of childhood recreation: my cousins and I swivel in the sand at the water’s edge.

(INVITED) On the mechanism leading to afterglow in Gd2O2S:Pr
Optical Materials: X, 2021 The performance of scintillator materials and phosphors for x-ray imaging is adversely affected by afterglow, giving rise to ghost images and thus compromising image quality.
