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.

Features and Benefits

• 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.
