The very red afterglow of GRB 000418 - further evidence for dust extinction in a GRB host galaxy [PDF]

open access: yes, 2000
We report near-infrared and optical follow-up observations of the afterglow of the Gamma-Ray Burst 000418 starting 2.5 days after the occurrence of the burst and extending over nearly seven weeks.

(INVITED) On the mechanism leading to afterglow in Gd2O2S:Pr

open access: yesOptical 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.

Temporal dusty plasma afterglow: A review

open access: yesFrontiers 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

Green Afterglow of Undoped SrAl2O4

open access: yesNanomaterials, 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–

Luminescent properties of Mg1.99SnO4:0.01Mn2+ phosphors doped with Zn2+

open access: yesJournal of Materiomics, 2023
In this work, a series of ZnxMg1.99-xSnO4:0.01Mn2+ (x = 0, 0.01, 0.02, 0.03, 0.04) green long afterglow phosphors are prepared by high-temperature solid-phase reaction. The photoluminescence and long afterglow performance of host material doped with Zn2+

Butterfly-Shaped Guest Molecules Enable Tunable Room-Temperature Phosphorescence in Host-Guest Doped Systems. [PDF]

open access: yesAdv Sci (Weinh)
Butterfly‐shaped triphenylamine‐based guest molecules (DBDBD) doped into rigid host matrices (TPP, CA) achieve efficient, multicolor‐tunable room‐temperature phosphorescence (RTP). The host‐guest synergy enables ultralong afterglow (up to 4 s) and quantum yields (Φp = 3.42%), with applications in dynamic anti‐counterfeiting and information encryption ...

Inclination Estimates from Off-Axis GRB Afterglow Modelling

open access: yesUniverse, 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.

Gamma Ray Bursts vs. Afterglows [PDF]

open access: yes, 1998
When does a GRB stop and its afterglow begin? A GRB may be defined as emission by internal shocks and its afterglow as emission by an external shock, but it is necessary to distinguish them observationally.

Afterglow Carbon Dots: From Fundamentals to Applications

open access: yesResearch, 2021
The ability of carbon dots (CDs) to emit afterglow emission in addition to fluorescence in response to UV-to-visible excitation allows them to be a new class of luminescent materials.
