Polarization Sensitivity of Chiral Manganese Halide Scintillators Enables High‐Resolution X‐Ray Imaging

Advanced Functional Materials, EarlyView.
Highly luminescent chiral manganese halide crystals are synthesized using chiral ligands, and they exhibit dissymmetry factors up to 1.4 × 10−2 and show X‐ray detection scintillation capability with a light yield of 43 380 photons/MeV and a low detection limit of 0.05198 µGyair·s−1.

Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells

Advanced Functional Materials, EarlyView.
Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

Si‐Doped Nanocrystalline Diamond as Highly Sensitive Luminescence Thermometer for the Physiological Temperature Range

Advanced Functional Materials, EarlyView.
In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.
