Surface ligand engineering of Ag2Te colloidal quantum dots for a self-powered shortwave infrared photodetector
Ag2Te colloid quantum dots (CQDs) are synthesized using bifunctional thiol ligands, and a high-performance and self-powered Ag2Te CQD-based shortwave infrared photodetector is constructed for non-contact pulse monitoring.
Mn2+-doped Cs3Cu2I5 halides and their application in high resolution X-ray imaging and thermal neutron detection
Mn2+-doped Cs3Cu2I5 powders prepared via solution show enhanced PL, reduced self-absorption, and achieve 16 lp mm−1 X-ray resolution. With 6LiF, yield reaches ~24 500 photons/neutron, 3.5 × GS20, with clear n–γ discrimination for radiation detection.
Enhanced X-ray detection of one-dimensional DABCO–NH4I3 perovskites via anisotropic carrier transmission study
One dimensional metal-free perovskite DABCO–NH4I3 displays anisotropy of carrier transport in different crystal directions.
Tunable optical and scintillation properties of two-dimensional tin mixed-halide perovskites
The controllable doping of hybrid organic–inorganic perovskites fueled strong interest as scintillating materials.
A metal-free molecular pyroelectric material with strong pyro-photovoltaic coupling for enhancing self-powered X-ray response
We report metal-free pyroelectric materials with tunable pyroelectric via molecular design. The top candidate enables self-powered X-ray detection through photo-pyroelectric effects. This work advances the development of optoelectronic materials.
High resolution X-ray imaging via near unity emission organic–inorganic manganese bromide scintillator films using a suction filtration method
In recent years, lead-free organic–inorganic hybrid scintillators have attracted much attention in the field of X-ray imaging because of progress in their solution synthesis, low toxicity, and high photoluminescence quantum yield (PLQY).
High-throughput growth of organic scintillating single crystal fibers for neutron/gamma pulse shape discrimination
A mold-embedded growth method is presented for the batch production of organic scintillating single crystal fibers (SCFs). These SCFs can be integrated into a pixelated scintillator array, showing high performance in neutron detection.
About this collection
This themed collection focuses on novel materials and devices for the sensitive detection of photons and for the conversion of high energy ionizing radiation. The focus is mainly on organic semiconductors and metal halide perovskites, although the themed collection is open to the submission of alternative materials. The topics focus on electromagnetic radiation detection beyond the visible range. Novel developments on active materials both for direct detection and for indirect detection (scintillators) are covered by the themed collection.
This Journal of Materials Chemistry C themed collection on ‘Novel materials and devices for photon and ionizing radiation detection’ in collaboration with Symposium P at E-MRS Spring 2025 is Guest Edited by Professor Andrea Ciavatti (University of Bologna, Italy), Professor Francesca Cova (University of Milano-Bicocca, Italy), Professor Michele Sessolo (University of Valencia, Spain). We hope that this collection will give readers an overview of some of the most recent work concerning the materials chemistry of novel materials and devices for photon and ionizing radiation detection and will help to promote exciting research in the field.
