Mechanism of thermoluminescence in magnesium oxide
Abstract Thermoluminescence (TL) induced by γ-rays in nominally pure polycrystalline MgO powders has been investigated. In addition to a high temperature peak around 650 K, which is also present in the unirradiated specimens, TL glow peaks are observed around 365, 435, 510 and 545 K. The role of tra...

520 | |a Abstract Thermoluminescence (TL) induced by γ-rays in nominally pure polycrystalline MgO powders has been investigated. In addition to a high temperature peak around 650 K, which is also present in the unirradiated specimens, TL glow peaks are observed around 365, 435, 510 and 545 K. The role of transition metal impurities on TL behaviour has been studied by the doping technique. It is observed that $ Cr^{3+} $, $ Mn^{2+} $ and $ Ni^{2+} $ act as emission centres while $ Fe^{3+} $, $ Co^{2+} $ and $ Cu^{2+} $ act as quenchers. For a particular sample all γ-induced glow peaks give a similar emission spectrum which is characteristic of the activators present. Optical bleaching, isothermal decay and ESR studies have been used to study the trapping centres. It is shown that the charge carriers involved are holes from V-type defects. The dominant 365 K peak has been assigned to $ V_{M} $ centres. A hole-release mechanism involving recombinations with electrons trapped at activators is proposed to explain the TL behaviour. | ||

Mechanism of thermoluminescence in magnesium oxide |
abstract |
Abstract Thermoluminescence (TL) induced by γ-rays in nominally pure polycrystalline MgO powders has been investigated. In addition to a high temperature peak around 650 K, which is also present in the unirradiated specimens, TL glow peaks are observed around 365, 435, 510 and 545 K. The role of transition metal impurities on TL behaviour has been studied by the doping technique. It is observed that $ Cr^{3+} $, $ Mn^{2+} $ and $ Ni^{2+} $ act as emission centres while $ Fe^{3+} $, $ Co^{2+} $ and $ Cu^{2+} $ act as quenchers. For a particular sample all γ-induced glow peaks give a similar emission spectrum which is characteristic of the activators present. Optical bleaching, isothermal decay and ESR studies have been used to study the trapping centres. It is shown that the charge carriers involved are holes from V-type defects. The dominant 365 K peak has been assigned to $ V_{M} $ centres. A hole-release mechanism involving recombinations with electrons trapped at activators is proposed to explain the TL behaviour. © Chapman and Hall Ltd. 1978 |
