Our earlier ESR studies on the thermoluminescent (TL) phosphor BaSO 4 :Eu, P indicated the involvement of two SO 2 - radicals in the TL process and co-doping BaSO 4 :Eu (0.5 mol%) with phosphorus (0.2 mol%) enhanced its TL efficiency by 5.3 times. Th

The paramagnetic radicals formed in the TL phosphors BaSO4:Eu and BaSO4:Eu, P have been studied using the technique of ESR. Two radicals, assigned to SO2-, were observed at room temperature. One of them exhibits a hyperfine interaction with a nearby

The Mossbauer effect is the recoil-free emission and resonant absorption of γ-rays by specific atomic nuclei in sohds. The γ-rays can be used as a probe of nuclear energy levels which are sensitive to the local electron configuration and the electr

The defect centres formed in the thermoluminescent phosphor CaSO4:Dy on additionally doping with Na+ (as a charge compensator) have been studied using the technique of electron paramagnetic resonance. The Na+ ion at the Ca2+ site is found to stabiliz
