Systematic investigation of the diffraction efficiency of sub‐15 nm resolution soft X‐ray zone plates via simulation and measurement

Journal of Synchrotron Radiation, EarlyView.
This study presents systematic measurements and rigorous coupled‐wave analysis of relative and absolute diffraction efficiencies for sub‐15 nm soft X‐ray Fresnel zone plates. By decoupling intrinsic optical performance from practical beamline transmission losses, this work establishes a highly reliable metrology framework to support the development of ...

Application of Silicon Photomultipliers in Neutron Detectors [PDF]

, 2021
Advancement in the development of semiconductor photodetectors have led to substitution of Photomultiplier Tube (PMT) technology by solid state devices in many applications. Silicon Photomultipliers (SiPM) are solid-state photodetectors with a gain similar to PMT and that have several advantages over the PMTs like low operating voltages and ...

Fast-gated digital silicon photomultiplier maximizes light harvesting and depth sensitivity in time-domain diffuse optics [PDF]

, 2021
We show both on phantoms and in-vivo the full potential of fast time-gated acquisitions exploiting an innovative custom-developed digital silicon photomultiplier, overcoming consolidated limitations showed by single-photon avalanche diodes linked to ...

Switchable Dual Emission of Luminescent Metal–Organic Framework@Nanoparticle Composites of EuBDC and ZrO‐Containing Hybrid Materials

European Journal of Inorganic Chemistry, Volume 29, Issue 26, 16 September 2026.
Luminescent metal–organic framework@nanoparticle composites show dual emission of both components EuBDC and zirconyl‐containing nanoparticles, being reversible, excitation energy‐dependent and solvatochromic switches. The chromaticity changes are fast, as no chemical transformation is involved and required as source of the dual emission.

Solution‐Processed Mn‐Doped 2d Perovskite Wavelength Shifters for Noble‐Liquid Photon Detection

Advanced Functional Materials, Volume 36, Issue 74, 14 September 2026.
Solution‐processed Mn2+‐doped PEA2PbBr4 two‐dimensional perovskite films are demonstrated as large‐area wavelength shifters for noble‐liquid photon detectors. Mn2+ incorporation introduces a broad emission band at ∼620 nm with a large Stokes shift, suppressing self‐absorption and matching SiPM sensitivity.

Thermal and electrical characterization of silicon photomultiplier

2007 IEEE Nuclear Science Symposium Conference Record, 2007
Detection of low levels of light is one of the key aspects in medical and space applications. Silicon photomultiplier, a novel type of avalanche photodetector which operates in Geiger mode, shows promising results and offer superior design options. The performance characteristics of the SiPM realized in FBK-irst are studied and presented in this paper.

Magnetic field dependence studies for silicon photomultiplier

, 2004
The Silicon Photomultiplier (SiPM) is a relatively new semiconductor photodetector, which has comparable performance properties to conventional vacuum multi-anode Pho- tomultiplier. One possible application for this new kind of photodetector is the usage

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Halogen Surface Terminations in Ti3C2 MXenes for Interface Engineering in Perovskite Solar Cells

Advanced Materials Interfaces, Volume 13, Issue 18, 22 September 2026.
Controlled halogen surface terminations in Ti3C2${\rm Ti}_3{\rm C}_2$ MXenes enable the isolation of structure‐property relationships, revealing how –Cl and –Br terminations influence interlayer spacing, electronic behavior, and work function. When incorporated into IT‐4F‐based interfacial layers, these MXenes modulate interfacial processes and device ...
