Collisionless adiabatic afterglow [PDF]
Physics of Plasmas, 2020 We study, by numerical and analytical means, the evolution of a collisionless plasma initiated between absorbing walls. The ensuing flow is described by rarefaction waves that travel inward from the boundaries, interact, and eventually vanish after crossing through, leading up to the asymptotic stage of the decay. Particle simulations indicate that the

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

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 ...

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.

Complex Plasma Afterglow [PDF]
Contributions to Plasma Physics, 2009 AbstractIn complex plasmas, dust particles are charged through their interactions with the electrons and the ions of the surrounding plasma. In laboratory discharges, when the discharge is turned off, the charged species of the plasma diffuse away and recombine into neutral species.

Narrowband Organic/Inorganic Hybrid Afterglow Materials
MoleculesNarrowband afterglow materials display interesting functions in high-quality anti-counterfeiting and multiplexed bioimaging. However, there is still a limited exploration of these afterglow materials, especially for those with a full width at half maxima

Angewandte Chemie, EarlyView.Multiphase systems, including ones with liquid‐liquid phase boundaries, are the home to many curious chemistries including reaction acceleration and spontaneous formation of reactive species. Here we show the liquid‐liquid interface causes electrochemiluminescence and afterglow chemiluminescence lifetime to be enhanced by 220,000% in‐time, far beyond ...
