Cesium Carbonate (Cesium Carbon Oxide), Powder, 99.998%, -100 mesh approx

Cesium carbonate is widely used as an interfacial layer or dopant in organic light-emitting diodes (OLEDs) and polymer solar cells to enhance electron injection and improve device efficiency.

Used as a precursor material in the preparation of specialized sputtering targets for depositing thin films that require low work function surfaces or alkali metal doping.
