Descripción general

Cesium bromide (CsBr) is an inorganic compound moderately soluble in water and exhibits hygroscopic properties. CsBr crystals are utilized in scintillation counters for detecting radiation due to their effective scintillation properties. It is also used in optics as a beam splitter component in wide-band spectrophotometers.

Aplicación

Cesium bromide can be used as:      
  • An electrolyte additives to improve the cycling efficiency of lithium and graphite anodes in lithium-ion batteries. The cesium cations can help control the interfacial chemistry on the anode, leading to enhanced performance.     
  • An additive to enhance the efficiency and stability of CsPbI2Br perovskite solar cells by passivating defects, improving charge transport properties, and contributing to higher power conversion efficiencies.
  • As a precursor material to synthesize cesium lead bromide (CsPbBr3) perovskite, which is then utilized as an electrode material in a symmetric supercapacitor.  
  • As a precursor to prepare thermal neutron imaging plates.     
  • As a precursor to synthesize lead-free CsBr: Eu2+ nanocrystals for fabricating white LEDs.    
  • As an additive to prepare CsI-based scintillators. Alloying with cesium bromide increases the yield limit and microhardness of CsI crystals.

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.
