Abstract
CsCl crystals grown from water solution give a broad fluorescence emis sion between 340 nm and 500 nm due to the OH- ions embedded in the lat tice, which are also responsible for the 267 nm absorption band observ ed in these crystals. Eu doped CsCl crystals give a prominent emission with maximum at 440 nm, due to the divalent Eu ions. The emission due to OH- ions is also observed in CsCl:Eu crystals.
