Applications

Cesium iodide is used in FT-IR (Fourier Transform Infrared Spectrometers) as a beamsplitter. Cesium Iodide exhibits high gamma-ray stopping power. Useful as input phosphor in fluoroscopy equipment, and efficient photocathode for extreme ultraviolet wavelengths. Fast and dense scintillating material - useful in electromagnetic calorimetry in particle physics.

Notes

Resistant to thermal and mechanical shock. Slightly hygroscopic in nature.
