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+

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.

Ratiometric afterglow luminescent nanoplatform enables reliable quantification and molecular imaging

open access: yesNature 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 ...

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

open access: yesPhotoMat, 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

Effective scintillation materials based on solid solutions ZnS1–xTex and perspectives of their application [PDF]

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2011
The optimal technological regime of formation ZnS1–xTex solid solution at spacing 0,0≤х≤0,1 has been determined, and has been shown that fritting in hydrogen atmosphere results in more rapid reaction in comparison to argon due to chemical-thermal etching

Narrowband Organic/Inorganic Hybrid Afterglow Materials

open access: yesMolecules
Narrowband 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

GRB 221009A: Revealing a Hidden Afterglow during the Prompt Emission Phase with Fermi-GBM Observations

open access: yesThe Astrophysical Journal Letters, 2023
Recently, LHAASO reported the detection of the brightest-of-all-time GRB 221009A, revealing the early onset of a TeV afterglow. We analyze the spectral evolution of the X-ray/gamma-ray emission of GRB 221009A measured by the Fermi Gamma-ray Burst Monitor
