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.
