Facile, Scalable, and High‐Yield Synthesis of a Near‐Unity Quantum Yield Zero‐Dimensional Copper Halide Cs3Cu2Cl5 Scintillator for X‐Ray Imaging

Advanced Optical Materials, Volume 14, Issue 36, 25 September 2026.
A dioxolane‐mediated reaction synthesis provides a simple and scalable route to phase‐pure Cs3Cu2Cl5 scintillator powders with near‐complete conversion, near‐unity photoluminescence quantum yield, and long‐term stability. The resulting green‐emitting composite films exhibit strong radioluminescence, high light yield, and practical compatibility with ...

Co‐Firing Slow Solidification Process for Growing Indium‐Doped Cs3Cu2I5 Single Crystals With Record‐Breaking X‐Ray Detection Performance

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.

Thermoluminescence and radioluminescence of alexandrite mineral

Journal of Luminescence, 2019
Abstract The thermoluminescence (TL) of natural alexandrite (BeAl2O4) was investigated using different methods, namely Tm-Tstop, Tm as a function of beta irradiation dose, glow curve best fitting, variable heating rate, and TL fading as a function of time after irradiation, in addition to radioluminescence (RL) measurements under X-ray excitation as ...
