RADIATION-INDUCED CONDUCTIVITY OF AS-GROWN AND ELECTRODIFFUSED QUARTZ

Thermoluminescence, phosphorescence, and ac conductivity measurements have been performed at room temperature on as-grown or Li-, Na-, and Cu- electrodiffused synthetic quartz, beta or x ray irradiated, to confirm the ionic nature of the charge carriers in the radiation-induced conductivity (RIC). Comparison between RIC and phosphorescence time dependence has allowed us to propose a mechanism for the annealing process of the RIC.
