Thermoluminescence and Optical Absorption of Lizardite crystals

Creators

Description

Pellets of lizardite crystals (Mg3 [Si,Fe]2O5 (OH)4]) and teflon powder have been investigated to identify the centers related to thermoluminescence (TL) emission. All the Tl peaks are well fitted by using a second order kinetic model and the related trap parameters and activation energy are evaluated. Moreover, the measured optical absorption bands, in the visible and UV ranges, and in the infrared region, are attributed to charge transfer involving Mn and Fe ions and to vibration modes of Mg-O-H groups, respectively
