Abstract
The luminescent properties of gradient activated crystals of lithium niobate with the concentration profiles of the optical centers of ytterbium and erbium ions are studied. It is shown that the spectral-luminescent properties of the gradient crystal are correlated with the concentration profiles of the optical centers of Yb3 + donors and Er3+ acceptors.
