Applicazioni

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.

Caratteristiche e vantaggi

Frequently used in devices such as phosphor screens for medical imaging, scintillators, calorimeters and a variety of particle detectors.

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..
