THERMOLUMINESCENCE OF L-TYROSINE UNDER U.V. IRRADIATION,

Abstract

The thermoluminescence of polycrystalline L-tyrosine kept at 77K during irradiation by u.v. light has been investigated. On the basis of action spectra, emission spectra, and decay kinetics, a phenomenological model is proposed in which the final radiative transition is from the lowest triplet to the ground singlet state of the molecule. The role of metal ions in trace amounts, various gases in contact with the sample, and a bleaching effect by white light were also studied. (Author)
