General description
Cesium carbonate is a mild inorganic base widely used inelectroluminescent devices and organic synthesis. Due to its excellent electroninjection capability, it is used as an interface modifying material in organiclight-emitting diodes (OLED), organic field effect transistors (OFET), organicsolar cells (OSCs), and perovskite solar cells.
Application
Cesium carbonate can be used as:
- A cathode buffer layer to enhance device stability and power conversion efficiency in polymer solar cells.
- A precursor to prepare alkali-based electrolyte for selective reduction of CO2 by electrocatalysis.
- A base in many organic transformations such as C, N, O alkylation, and arylation reactions.
Promotes the efficient O-alkylation of alcohols to form mixed alkyl carbonates.

Lead halide perovskite nanocrystals (NCs) exhibit excellent tunable emissions covering the entire visible spectral region, but they do not emit near-infrared (NIR) light. We synthesized rare earth element doped CsPbCl3 NCs for NIR emission. The Yb3+ doped CsPbCl3 NCs emitted
