Description
Time-resolved optically stimulated luminescence (TR-OSL) sensitivity and lifetimes on the various thermal treatment for natural zircon from Brazil were investigated. Analyses of the TR-OSL spectra have showed that the decay is composed of two exponential components with lifetimes depending on the sample treatments. This change of the lifetimes is discussed in terms of a model previously used to explain thermal sensitization. The luminescence lifetime data are best explained by the presence of two luminescence centers, depending on the thermal history.
