Abstract : The present work has extended the range of thermoluminescence measurements from a lower limit of 77 degrees K to 10 degrees K and has amplified the earlier work to include such effects as the dose dependence of the luminescence signal, measurement of the activation energy of the glow peaks, and the production of additional glow peaks in doped azide powders. There is no simple correlation between the thermoluminescence and the gas evolution, and the detailed study of the glow peaks at various heating rates showed that a comparison of the glow peaks and gas evolution could lead to error if one chose a single heating rate which caused the maxima to occur at a similar temperature. Measurements at several heating rates have shown that the two processes do not proceed at the same time.
