Electric Field Effect on the Spin Alignment of Triplet Traps of 4,4'-Dichlorobenzophenone Crystal.

Abstract

The spin alignment of triplet traps of the polar 4,4'-dichlorobenzophenone neat crystal is changed by applying an external electric field which results in a change of the phosphorescence intensity and phosphorescence microwave double resonance (PMDR) signals. This and the results of other experiments can best be explained if one assumes that the field modifies the triplet-rather than singlet - exciton dynamics. A possible field-induced change in the radiative properties of the spin levels of the shallow traps (13-17 per cm) is also observed. (Author)
