Application
Cesium iodide (CsI) can be used as a cathode for the fabrication of field emission cathodes for potential usage in high power microwave systems. It can also be used to form an interface layer between the blocking layer and the perovskite active layer to improve the photovoltaic performance and stability of solar cells.
Features and Benefits
- High purity of ≥99.995% Copper(II) chloride minimizes impurities, boosting efficiency and selectivity in catalytic processes essential for organic synthesis and industrial chemical production.
- The presence of low metal impurities in ≥99.995% copper(II) chloride ensure consistent quality in electroplating applications, enhancing adhesion and achieving uniform coatings on substrates without contamination that could compromise the finish.
- Anhydrous CuCl₂ reduces the risk of hydrolysis, preventing unwanted by-products and enhancing the efficiency of chemical processes.
Frequently used in devices such as phosphor screens for medical imaging, scintillators, calorimeters and a variety of particle detectors.
