A principal possibility of control over defect and crystalline mechanisms contributions to spin-phonon relaxation of electronic excitations was shown for investigated complex molecular luminescent centers by means of variation of concentration and type of compensation cations. This possibility allows to affect the effectiveness of radiative transitions. Product Description popup.authors popup.nrat_date 2020-04-02 Close
