Radioluminescence of annealed synthetic quartz

摘要

AbstractThe radioluminescence of synthetic quartz annealed at various temperatures up to 1000?°C is reported. The amplitude of the emission bands increases with annealing temperature. In addition, when samples are annealed at temperatures exceeding 700?°C, the intensity of the radioluminescence increases with duration of annealing. The corresponding emission spectra show seven emission bands at 2.04, 2.54, 2.77, 3.04, 3.40, 3.75 and 3.91?eV. The change in dominant emission band with annealing is consistent with annealing-induced variations in lifetimes determined previously from time-resolved optically stimulated luminescence spectra in the same samples.Highlights?Radioluminescence of synthetic quartz is reported.?The emission band amplitude increases with annealing temperature.?Beyond 700?°C, the intensity scales up with annealing temperature.?The emission spectra can be deconvoluted to 7 emission bands
