Abstract
This paper reports the thermo- and radio-luminescence of transition me tal-doped natural beryls. The luminescence was measured between 20 and 300K. Mn3+ and Cr3+ have been found to activate the thermoluminescenc e with a high degree of efficiency. Comparison of beryl:Ni, beryl:Co a nd aquamarine emission spectra with that of quartz suggests that in so me respects the beryl behaves as though it is a quartz and this has be en concluded to follow from similarities in the framework nature of bo th lattices.
