Abstract

Optically stimulated luminescence (OSL) dosimetry measurements using Cu¹⁺-doped fused quartz are reported. The OSL sensitivity of this material to ⁶⁰Co ? rays was found to be about twenty times greater than that measured previously for related Cu¹⁺-doped glasses that exhibit OSL sensitivity. The dose-response was measured from 0.13 to 51.6 µC.kg^-1 (0.5 mR to 300 mR) and is linear over this range. Spectral measurements of the photoluminescence, thermoluminescence and optically stimulated luminescence reveal that the Cu¹⁺ ions serve as the luminescence centres for recombination of both the TL and OSL traps. The results indicate that the TL and OSL traps in the Cu¹⁺-doped fused quartz are in some way related.
