From Data to Discovery: Machine Learning–Enabled Intelligent Characterization of Two‐Dimensional Materials

Advanced Intelligent Discovery, EarlyView.
Machine learning serves as a central engine for the intelligent characterization of two‐dimensional materials by integrating multimodal techniques, including optical microscopy, spectroscopy, electron microscopy, and scanning probe microscopy (SPM). This unified framework enables automated, high‐throughput, and quantitative extraction of structural ...

X-Ray Luminescence of YAG:Nd3+

Physica Status Solidi (a), 1983
The X-ray luminescence of the YAG:Nd crystals in the visible and UV range of the spectrum is studied. The position of the 2F25/2 level is determined to 37810 cm−1. The observed spectrum is ascribed to the transition from the afore-mentioned level to the SLJ states of the Nd3+ ions in YAG.

Luminescent x-ray polarimeter

SPIE Proceedings, 1994
A new type of sensitive X-ray polarimeter is proposed, based on the measurement of the azimuthal anysotropy of the angular distribution of the photoelectrons produced by photoabsorption of the infalling X-ray photons in the luminescent X-ray converter.

X‐RAY INDUCED VISIBLE LUMINESCENCE OF PORPHYRINS

Photochemistry and Photobiology, 1994
AbstractA concept has been presented whereby X‐ray irradiation can be used to induce visible luminescence of chromophores such as porphyrins. The essential aspects of the idea have been demonstrated in a supramolecular assembly consisting of a water‐dispersed polystyrene latex with an embedded scintillating compound, 2,5‐diphenyloxa‐zole, and an ...

X-ray fan-beam luminescence tomography

2014 IEEE 11th International Symposium on Biomedical Imaging (ISBI), 2014
Nanophosphors emit near-infrared (NIR) light upon x-ray excitation, and can be functionalized as probes for in vivo molecular imaging. X-ray luminescence imaging maps a distribution of nanophosphors for diagnostic and therapeutic purposes. In this paper, we propose an x-ray fan-beam luminescence tomography approach to quantify a spatial distribution of
