Özet

The optical absorption spectrum, luminescence and photoconductivity on single crystals PbMg1/3Nb2/3O3 and on ceramics Pb0.91La0.09(Zr0.65Ti0.35)O-3 are investigated in the wide temperature range. The luminescence spectrum correlates with the photoconductivity spectrum. The position of the maximum of the luminescent emission spectrum indicates the origin of the charge carriers emitted from the defect centers. On the basis of the data the properties of the local centers are determined, and the phenomenological approach to the relaxor theory is discussed.
