A Cocktail Approach Toward Tunable Organic Afterglow Systems [PDF]

, 2021
In this work, a cocktail approach toward tunable organic long-lived luminescence materials in solid, solution, and gel states is proposed. The tunable long-lived luminescence (τ > 0.7 s) is realized by controlling the energy transfer via manipulating the

GRB990123: Multiwavelength afterglow study [PDF]

, 2005
We report on the BeppoSAX and multiwavelength data analysis of the afterglow of Gamma-Ray Burst (GRB) 990123. Mainly due to its exceptional brightness, this is the only source for which the Wide Field Cameras have allowed an early detection of the X-ray ...

Photoinduced Triplet Depletion Allowing Higher-Resolution Afterglow

, 2023
Afterglow emission allows for imaging that is independent of autofluorescence under ambient conditions. Although higher-resolution afterglow is required for increasing the quality of the autofluorescence-free emission imaging, increasing the excitation ...

Concurrent tunable structural color, luminescence, and afterglow in single ZnS: X@SiO2 spheres via SiO₂-nanoarmor and calcination decoupling collaborative strategy. [PDF]

Smart Mol
For the first time, tunable structural color, luminescence, and afterglow are integrated into single ZnS:X@SiO2 spheres via a SiO2‐nanoarmor and calcination decoupling strategy, achieving 250–410 nm monodisperse wurtzite spheres with 91% phase conversion, 12.8% PLQY, and 12.27 s afterglow. Abstract The integration of structural color, photoluminescence,

Inclination Estimates from Off-Axis GRB Afterglow Modelling

Universe, 2021
For gravitational wave (GW) detected neutron star mergers, one of the leading candidates for electromagnetic (EM) counterparts is the afterglow from an ultra-relativistic jet.

Ratiometric afterglow luminescent nanoplatform enables reliable quantification and molecular imaging

Nature Communications, 2022
Afterglow luminescence is an internal luminescence pathway that occurs after photo-excitation, holds great promise for non-background molecular imaging in vivo, but suffer from poor quantitative ability owing to luminescent attenuation over time ...

Fermi-GBM Discovery of GRB 221009A: An Extraordinarily Bright GRB from Onset to Afterglow [PDF]

Astrophysical Journal Letters, 2023
We report the discovery of GRB 221009A, the highest flux gamma-ray burst (GRB) ever observed by the Fermi Gamma-ray Burst Monitor (Fermi-GBM). This GRB has continuous prompt emission lasting more than 600 s, which smoothly transitions to afterglow ...
