Description

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.

Packaging
