Abstract
Thermoluminescence of metals is not expected on ground of the theory. The effects which have been found for Cu, Fe, Cr, Zn, W and Mo might be regarded as due to the formation of oxygen containing superstructures with semiconducting properties in the surface regions. Both the emitted thermoluminescence energy and the temperature at which its peak in the glow curve is found for Cu and Mo, are influenced by the mode of the pretreatment of the sample. The values are found lower after previous cooling and higher after previous grinding or heating in a vacuum. For all metals under investigation the phenomenon of the so-called “contact-memory” has been found. The effects of thermal or mechanical pretreatment of the metal powders are also reflected in corresponding changes in adsorption behaviour. The results allow certain conclusions about the energy distribution over the various hierarchic levels.
