A Room‐Temperature X‐ray‐Induced Photochromic Material for X‐ray Detection

Angewandte Chemie International Edition, 2012
A color change: X-ray-induced photochromic species are rare and can be used for detection of X-rays. A highly robust X-ray-sensitive material with the discrete structure of a metal-organic complex has been found to show both soft and hard X-ray-induced photochromism at room temperature. A new ligand-to-ligand electron-transfer mechanism was proposed to

Metal‐Free Perovskites for X‐Ray Detection

Chemistry – A European Journal, 2023
AbstractMetal‐free perovskites are a promising class of materials for X‐ray detection due to their unique structural, optical, and electrical properties. Here, we first delve into the stoichiometry and geometric argument of metal‐free perovskites. Followed, the alternative A/B/X ions and hydrogen‐bonding are clearly introduced to further optimize the ...

X-Ray Fluorescence-Detected Flow Cytometry

2018
X-ray fluorescence-detected flow cytometry can enable the detection and characterization of ultra-trace, trace, and bulk elemental content at the cellular level using synchrotron-induced x-ray emission from fully aquated actively respiring cells. Although very much still a technique in development, this technique has been used to characterize cell-to ...

Detectability of lunar X-rays

Planetary and Space Science, 1965
Abstract We have examined several theories that imply the generation of X-rays by the Moon. The X-ray fluxes to be expected at the top of the Earth's atmosphere are estimated and compared. For example, we find that an X-ray flux is to be expected when the Moon is full and K p high, as a consequence of the configuration of the auroral electrons ...

Perovskites for x-ray detection

Organic and Hybrid Sensors and Bioelectronics XIV, 2021
Hybrid perovskite materials are attractive for detection of X-ray and gamma-ray in both direct and indirect ways. The high stopping power of perovskites as well as excellent charge transport properties enables direct detection of single photon gamma ray in photon counting mode.

GaN for x-ray detection

Applied Physics Letters, 2008
The potential of GaN based materials for x-ray detection is investigated. The absorption coefficient in GaN is measured as a function of photon energy between 6 and 40keV. Metal-semiconductor-metal photodetectors are fabricated and characterized. The response dependence on bias, the temporal dynamics, and the response dependence on detector geometry ...

Soft X-Ray Image Detection

SPIE Proceedings, 1989
Techniques for the detection of soft x-ray images are discussed. Specific needs for gray level detection are considered. A camera system using a COD sensor, which meets the needs for soft x-ray image detection is presented, and x-ray microscope images, taken with this camera are presented.

Element Selective X-ray Detected Magnetic Resonance

AIP Conference Proceedings, 2007
Abstract Element selective X-ray Detected Magnetic Resonance (XDMR) was measured on exciting the Fe K-edge and Y L-edges in a high quality Yttrium Iron Garnet (YIG) thin film. Resonant pumping at high microwave power was achieved in the non-linear foldover regime and X-ray Magnetic Circular Dichroism (XMCD) was used to probe the time-invariant change

Scintillation Counter for Detection of X-Rays*

Journal of the Optical Society of America, 1955
A scintillation counter using NaI(Tl) is described. The sensitivity is such that the yield of photoelectrons is about 3.5 per 1000 ev x-ray energy. The response is linear over a range in intensity of 5×105.
