Implication

Experimental study demonstrates thermoluminescence glow characteristics in aragonite and magnesite, indicating distinct trap distributions across carbonate minerals.

Key Points

  • Investigate the thermoluminescence mechanisms, glow peak behaviors, and electron trapping characteristics of aragonite and magnesite minerals.
  • Subjected natural and synthetic specimens of aragonite and magnesite to thermal excitation following radiation exposure.
  • Recorded glow curves and luminescence intensity as a function of temperature to determine activation energies and trap depths.
  • Demonstrated prominent thermoluminescence glow peaks corresponding to discrete electron trap levels within the aragonite and magnesite crystal lattices.
  • Showed that luminescence emission spectra and trap kinetics depend directly on crystal symmetry and the presence of trace impurity activators.
