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.

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

This paper presents detective quantum efficiency (DQE) data measured for a range of x-ray beam qualities for two full-field digital mammography (FFDM) systems: a caesium iodide (CsI) detector-based unit and a system designed around an amorphous selenium (a-Se) x-ray detector.

Optics express, 17(23), 20684-20693 (2009-12-10)
We present a versatile terahertz time-domain spectrometer which allows reflection measurements at normal incidence and double pass transmission measurements in a single experimental setup. Two different modes for transmission measurements are demonstrated for precise measurements of transparent high or low
