ResumoOptically stimulated luminescence processes in feldspars are subject to competing thermal enhancement and quenching processes: this article describes the thermal enhancement effects for orthoclase, albite and plagioclase feldspars. It is demonstrated that certain lattice vibrational modes can be selectively probed at specific optical excitation energies. The results are described in terms of the Bohr hydrogen model of the OSL donor defects.
