Application

Cesium iodide can be used as precursor to synthesize lead-free perovskite material, Cs2NaBiI6 (CNBI). The CNBI is highly stable and finds application in the field of solar cells, LEDs, and lasers.

It can be used to prepare brightest red emitting Cs2HfI6 scintillator which is applicable in high resolution gamma spectroscopy.

It can also be used tosynthesize Cesium based nanocrystals for the detection of ionizingradiations.

Caractéristiques et avantages

  • High quantum efficiency
  • High stability to ambient air and gas environment
Frequently used in devices such as phosphor screens for medical imaging, scintillators, calorimeters and a variety of particle detectors.

Alkali halide systems that function as phase-separated scintillators (PSSs) with light-guiding properties are sucessfully created. Furthermore, it is the matrix phases of the PSSs which display the light-guiding properties. CsI-NaCl:Tl is a practical material pair because of its high pixel

A small-sized thermal neutron detector based on a (6)Li-glass scintillator and a plastic optical fibre has been developed for precise measurement of the spatial distribution of thermal neutron fluence rate. This detector was tested in experiments performed using thermal neutrons.

We study the reorientation dynamics of water molecules around ions using terahertz dielectric relaxation spectroscopy and polarization-resolved femtosecond infrared pump-probe spectroscopy. The results are discussed in relation to the ion-specific Hofmeister series and the concomitant "structure-making" and "structure-breaking" effects of

The purpose of this study is to compare digital radiography systems using the metric effective detective quantum efficiency (eDQE), which better reflects digital radiography imaging system performance under clinical operating conditions, in comparison with conventional metrics such as modulation transfer

Accurate models of detector blur are crucial for performing meaningful optimizations of three-dimensional (3D) x-ray breast imaging systems as well as for developing reconstruction algorithms that faithfully reproduce the imaged object anatomy. So far, x-ray detector blur has either been

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.
