AbstractThis paper reports the thermo- and radio-luminescence of transition metal-doped natural beryls. The luminescence was measured between 20 and 300K. Mn3+ and Cr3+ have been found to activate the thermoluminescence with a high degree of efficiency. Comparison of beryl:Ni, beryl:Co and aquamarine emission spectra with that of quartz suggests that in some respects the beryl behaves as though it is a quartz and this has been concluded to follow from similarities in the framework nature of both lattices. © 1995.
