Optical absorption, photo-and thermo-luminescence measurements were performed on (NaPO3)x(GdPO4)y(TbPO4)z(x = 60-77 mol%; y = 20-30 mol%; z = 3-10 mol%) glasses. Pronounced changes of photoluminescence intensity of the leading 542 nm emission line of Tb3+were observed during prolonged excitation (irradiation) by 308 nm XeCl excimer laser line into the Gd3+ 6P5/2excited state. Laser irradiation also gave rise also to optical absorption that peaks at around 5.4 MeV and to a thermoluminescence glow peak at 195°C. Similar optical absorption and thermoluminescence features were found by ionising (X-ray) irradiation. The results are explained by taking into account energy exchange between the Gd-sub-lattice and deep traps in the glass matrix. © 2001 Elsevier Science Ltd.
