Caesium phosphate, Cs3PO4, is a phosphate of caesium[1] that is highly soluble in water.
Use
[edit]Caesium phosphate can be used as an n-dopant to enhance the conductivity of the electron transport layer in organic light-emitting diodes.[2]
Related compounds
[edit]Several caesium hydrogen phosphates (CsxHy(PO4)z·nH2O) have been characterized.[3][4]
Several mixed phosphates such as caesium–manganese phosphate (CsMnPO4),[5] caesium–cobalt phosphate (CsCoPO4),[6] and caesium–magnesium phosphate (CsMgPO4)[7] also exist.
