【 摘 要 】

Spatial and temporal distribution of quantum efficiency of energy transfers in crystals of lithium niobate with non-uniform concentration profiles of Er3+and Yb3+ions has been studied for the cases of Yb3+-Er3+Foerster transfer and radiative decay of upper energy levels of erbium ions (green and red luminescence).
