Cesium Oxide History
L. R. Koller described the first modern photoemissive surface in 1929–30 as a layer of caesium on a layer of caesium oxide on a layer of silver.
Cesium Oxide Uses
Cesium Oxide (CAS NO.20281-00-9) is used in photocathodes to detect infrared signals in devices such as image intensifiers, vacuum photodiodes, photomultipliers, and TV camera tubes. It is a good electron emitter; however, its high vapor pressure limits its usefulness.
Cesium Oxide Safety Profile
Ignition or incandescent reaction on contact with water; ethanol; moisture + carbon monoxide or carbon dioxide; sulfur dioxide + heat; or halogens (fluorine; chlorine; or iodine) above 150°C. Reacts with H2O. with formation of CsOH. See also CESIUM.
RIDADR: 3180
