Continuous Condensed Triplet Accumulation for Irradiance‐Induced Anticounterfeit Afterglow

Advanced Science, 2023
Afterglow room‐temperature emission that is independent of autofluorescence after ceasing excitation is a promising technology for state‐of‐the‐art bioimaging and security devices.

Observational constraints on the afterglow of GRB 020531 [PDF]

, 2002
We present the data acquired by the TAROT automated observatory on the afterglow of GRB 020531. Up to now, no convincing afterglow emission has been reported for this short/hard GRB at any wavelength, including X-ray and optical.

Detailed optical and near-infrared polarimetry, spectroscopy and broadband photometry of the afterglow of GRB 091018: Polarisation evolution [PDF]

, 2012
[Abridged] A number of phenomena have been observed in GRB afterglows that defy explanation by simple versions of the standard fireball model, leading to a variety of new models.

Ratiometric afterglow luminescent nanoplatform enables reliable quantification and molecular imaging

Nature Communications, 2022
Afterglow luminescence is promising for non-background molecular imaging in vivo. Here the authors report a ratiometric afterglow luminescent nanoplatform to generate activatable afterglow probes for quantification of specific analytes including NO.

Photochemical afterglow of single organic molecules with wide‐range tunable lifetime

PhotoMat, EarlyView., 2023
“All‐in‐one” strategy was used to achieve photochemical afterglow in single organic molecule, with second‐to‐hour range tunable lifetime by tailoring the electron‐withdrawing ability of substituents. Abstract Background Photochemical afterglow that relies on slow release of photons from the chemical energy stored by light pre‐irradiation has emerged as

Coordination-Locked Engineering to Achieve Narrowband Room Temperature Phosphorescence in Non-Rare Earth Metal-Organic Frameworks. [PDF]

Adv Sci (Weinh)
In this contribution, the coordination‐locked phosphorescence amplification (CLPA) strategy is developed to successfully construct the first non‐rare‐earth narrowband RTP MOF crystal, Sr–tbc. In addition, Sr–tbc shows potential applications in high‐resolution afterglow display and multilevel information recognition.

Was the "naked burst" GRB 050421 really naked ? [PDF]

, 2011
A few long gamma-ray bursts such as GRB 050421 show no afterglow emission beyond the usual initial steep decay phase. It has been suggested that these events correspond to "naked" bursts that occur in a very low density environment.

The prompt optical/near-infrared flare of GRB 050904: the most luminous transient ever detected [PDF]

, 2006
With a redshift of z=6.295, GRB 050904 is the most distant gamma-ray burst ever discovered. It was an energetic event at all wavelengths and the afterglow was observed in detail in the near-infrared bands.

GRB 090510: a short burst from a massive star ? [PDF]

, 2011
GRB afterglow 090510 is (so far) the best-monitored afterglow in the optical, X-ray, and above 100 MeV, measurements covering 2-3 decades in time at each frequency.

Organic persistent room temperature phosphorescence enabled by carbazole impurity

Frontiers in Chemistry, 2023
The molecular design of metal-free organic phosphors is essential for realizing persistent room-temperature phosphorescence (pRTP) despite its spin-forbidden nature.
