Blue and infra-red stimulated luminescence in Cu+ doped fused quartz for application in radiation dosimetry

Cu+ was doped in fused quartz using simple technique and the BSL/IRSL and TL studies were carried out. The Cu+ doped quartz shows enhanced TL as well as OSL sensitivity compared to the undoped material. The OSL sensitivity with blue stimulation, in particular, is relatively high, about 13% of the commercially used OSL phosphor (Al2O3:C-Landauer Inc.) on the basis of initial OSL intensity measurements (i.e. luminescence averaged over first 3 s). Earlier works show that OSL/TL signals in natural quartz is stable and thus can be used in archeological dating and other dosimetric applications. The aim of the present study is to investigate TL/OSL characteristics of Cu+ doped fused quartz.

► Cu+ was doped in fused quartz using simple technique.
► The Cu+ doped quartz shows enhanced TL as well as OSL sensitivity.
► OSL sensitivity is about 13% of the commercially used OSL phosphor (Al2O3:C-Landauer Inc.).
► This phosphor may find applications in radiation dosimetry using OSL.
