Direct evidence for the participation of band-tails and excited-state tunnelling in the luminescence of irradiated feldspars

The significance and extent of band-tail states in the luminescence and dosimetry properties of natural aluminosilicates (feldspars) is investigated by means of studies using low temperature (10 K) irradiation and optically stimulated luminescence (OSL) stimulation spectroscopy, and thermoluminescence (TL) in the range 10–200 K, made in...
