✦ Synopsis

When the temperawe of a photoionized

TMPD3hlP glassy solution is suddenly raised from 77 K to 77 K + AT {JT -1 K), the recombination luminescence is enhanced, goes through a broad maximum and starts decaying. This is interpreted in terms of glass relaxation on warming. By means of a formally described model, the activation energy for electron detrnpping is found to be 0.65 eV. In our opinion this large vaiue indicates that electron detrapping is due to slow molecular rearrangements in the matrix.
