摘要：

Photoluminescence and thermoluminescence in BaSO4: Eu is reported. In earlier works, divalent Eu has been studied in BaSO4. In the present work Eu was incorporated as in predominantly Eu3+ or Eu2+ form. It is shown that RE3+ <-> RE2+ conversion or RE2+ <-> RE+ conversion is not an integral part of gamma induced TL. Eu3+ <-> Eu2+ conversion, on the other hand, may be important in UV induced TL. Low UV efficiency of this material is attributed to poor Eu3+ <-> Eu2+ conversion. This is in quite contrast to the analogus material CaSO4:Eu.
