Heated natural albite posseses a special property: it has strong thermoluminescence (TL) blue emissions under UV radiation. The TL glow curves of high albite after different times of UV exposure show PhotoTransferred ThermoLuminescence (PTTL) from deeps traps (345oC - 450oC) to shallow traps (150oC) which can be used to store UV damage. The point of inflexion of the process occurs after one hour under UV radiation, the low temperature peaks start gaining in intensity while the high temperature peaks stop dropping and stabilize into a plateau. Samples which have been subjected to UV radiation for 1 hour at different temperatures (RT, 70oC, 105oC and 140oC) give glow curves which display an increase of the maxima peaks according to temperature (up to 300oC). High albite, UV irradiated (for one hour) at 70oC displays a TL signal decrease of 30% after 1000 hours of storage at room temperature with high intensity emissions, for this reason this material could be a good UV dosimeter. | URI: | http://hdl.handle.net/10261/92066 |
