photoluminescence spectra and decay curves. It is found that the obtained samples are pure crystalline phases with garnet structure. The particles with a diameter ranging from 0.3 to 1 m show irregular shapes and have a tendency to be agglomerating. This host can be excited by ultraviolet (UV) light
and it exhibits a broad-band green emission in the region from 400 to 700 nm
