Thermoluminescence trapping

  1. Jul 10, 2015 #1
    When thermo-luminescent materials are illuminated with UV or deep blue, luminescent centers can be excited or even ionized so that the electron gets trapped into a level just below the conduction band, typically 0.4 to 1 eV.
    Why is it that the trapped electrons are not released from the trap again by the excitation source? I would expect that there are enough levels to go to high in the conduction band or at least there may be trap energies where this could happen.
    Thanks!
