Dosimetric features of strontium orthosilicate (Sr2SiO4) doped with Eu2

Thermoluminescence (TL) of strontium orthosilicate doped with Eu2+has been investigated in the range RT-750K. Trap parameters of a TL peak at 450K established by means of glow curve analysis suggest the possibility of applying this sensitive peak for TL dosimetry. The thermal stability test shows th...

Description
Summary:Thermoluminescence (TL) of strontium orthosilicate doped with Eu2+has been investigated in the range RT-750K. Trap parameters of a TL peak at 450K established by means of glow curve analysis suggest the possibility of applying this sensitive peak for TL dosimetry. The thermal stability test shows that the 450K peak is partially unstable. The isothermal decay experiments reveal that the traps responsible for this peak can be emptied by a competitive way that is efficient during storage at a constant temperature, and is characterized by lower values of activation energy and frequency factor. •New efficient phosphor material was found for luminescence dosimetry.•Linear themoluminescent (TL) response was observed in wide range of beta doses.•Trap parameters were determined by glow curve analysis.•Isothermal TL measurements were performed and significant TL fading is reported.
