Chemical compound

Caesium monoxide or caesium oxide is a chemical compound with the chemical formula Cs₂O. It is the simplest and most common oxide of the caesium. It forms yellow-orange hexagonal crystals.

Uses

Caesium oxide is used in photocathodes to detect infrared signals in devices such as image intensifiers, vacuum photodiodes, photomultipliers, and TV camera tubes L. R. Koller described the first modern photoemissive surface in 1929–1930 as a layer of caesium on a layer of caesium oxide on a layer of silver. It is a good electron emitter; however, its high vapor pressure limits its usefulness.

Reactions

Elemental magnesium reduces caesium oxide to elemental caesium, forming magnesium oxide as a side-product:

Cs₂O + Mg → 2 Cs + MgO

Cs₂O is hygroscopic, forming the corrosive CsOH on contact with water.
