Abstract

Peculiarities in the crystal structure and spectral-luminescent properties of compound oxide systems Y3Al5O12:Ce3+/Lu2O3 and Lu3Al5O12:Ce3+/Lu2O3 are studied using the neutron diffraction and optical spectroscopy methods. The influence of the introduced oxide on the structural and luminescent properties of those systems is shown to have a complicated character depending not only on the formation of a stable defect garnet structure and the diffusion of Ce3+ ions from the matrix into the oxide, but also on the interaction between the oxide and the matrix, which gives rise to the formation of new phases.
