In search of progenitors for supernova-less GRBs 060505 and 060614: re-examination of their afterglows

, 2009
GRB060505 and GRB060614 are nearby long-duration gamma-ray bursts (LGRBs) without accompanying supernovae (SNe) down to very strict limits. They thereby challenge the conventional LGRB-SN connection and naturally give rise to the question: are there ...

Blue and NIR Upconversion in Tm3+/Yb3+ Co‐Doped Yttrium Pyrogermanate Phosphor for High‐Sensitivity Optical Thermometry

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
Y2Ge2O7:Tm3+/Yb3+ phosphors synthesized via solid‐state method exhibit efficient blue and NIR upconversion luminescence under 980 nm excitation, enabled by cooperative energy transfer from Yb3+ to Tm3+. The system demonstrates excellent optical thermometry performance, achieving a maximum absolute sensitivity of 156.42 × 10−2 K−1 and relative ...

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Advanced Functional Materials, Volume 36, Issue 3, 8 January 2026.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

GRB000301C with peculiar afterglow emission [PDF]

, 2000
The CCD magnitudes in Johnson V and Cousins R and I photometric passbands are determined for GRB 000301C afterglow starting ~ 1.5 day after the gamma-ray burst. In fact we provide the earliest optical observations for this burst.

A magnetar powering the ordinary monster GRB 130427A?

, 2014
We present the analysis of the extraordinarily bright Gamma-Ray Burst (GRB) 130427A under the hypothesis that the GRB central engine is an accretion-powered magnetar.

Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

Advanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.
