Abstract

The thermal history of a material with initially filled trap states has been probed using the thermoluminescence of microparticle sensors. Mg 2SiO4:Tb,Co particles with two thermoluminescence peaks have been heated using microheaters over a 230°C to 310°C range for durations of less than 200ms. The effect of maximum temperature during excitation on the intensity ratio of the peaks is compared with first-order kinetics theory and shown to match within an average error of 4.4%.
