Conference paper


The Vk centre + electron recombination luminescence is subject to quenching in the singlet emission band and intensified in the triplet band with applied magnetic field due to the incomplete electron spin polarization. The temporal run of the intensity at T<1 K reflects roughly the ground state F centre spin lattice relaxation time.
