Defect pair mechanism for quartz intermediate temperature thermoluminescence bands

The well-known 160 °C and 220 °C intermediate temperature bands in quartz thermoluminescence are attributed to the same defect reaction pair proposed previously to explain the 110 °C predose band. In particular, the trend towards longer spectral wavelengths as the glow proceeds across the 110 °C, 160 °C and 220 °C bands is shown to be consistent with the known energy levels of the [AlO4−/h+]0 substitutional defect.
