Applicazioni

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.

Caratteristiche e vantaggi

  • 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.

Alkali halide systems that function as phase-separated scintillators (PSSs) with light-guiding properties are sucessfully created. Furthermore, it is the matrix phases of the PSSs which display the light-guiding properties. CsI-NaCl:Tl is a practical material pair because of its high pixel

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.

Il team dei nostri ricercatori vanta grande esperienza in tutte le aree della ricerca quali Life Science, scienza dei materiali, sintesi chimica, cromatografia, discipline analitiche, ecc..
