THERMOLUMINESCENCE AND ESR OF BORON-STABILIZED BETA-DICALCIUM SILICATE

Thermoluminescence and ESR in boron-stabilized β-dicalcium silicate have been studied before and after ultraviolet irradiation. Most of the results, apart from the electron spin resonance signals from impurity iron and manganese, can be explained on the basis of electron location on the substituent BO4 groups replacing silicate tetrahedra, with electron capture at this centre being responsible for the thermoluminescence. © 1990 Chapman and Hall Ltd.
