Thermoluminescence studies on NaF-B2O3 glasses doped with certain transition metal ions

The alkali fluoroborate glasses like NaF-B2O3 glasses are considered as goo d materials for radiation dosimetry applications. The thermoluminescence (T L) propel ties of X-ray irradiated (pure and doped with four different tran sition metal ions viz.. Cu2+, V5+, Ti4+, and Mn4+) NaF-B2O3 glasses have be en studied. The activation energies anti various trap depth parameters or T L Flow curves have been evaluated. The possible use of these glasses in rad iation dosimetry has been described. Doping of some transition metal ions i nto NaF-B2O3 glasses may bring interesting changes in thermoluminescence (T L) emission characteristics of NaF-B2O3 glasses because some ol these ions may act as luminescence activators (whose energy difference between ground state and excited state lie in general between 1.5-3.0 eV) and some may act as killers since they have the property of a radiationless transition from the excited stale to ground state.
