typical transitions of Tb

respectively
and the strongest one appears at 548 nm.The excitation spectrum contains a broad band extending from 200 nm to 400 nm
which is coupled well with the emission of ultraviolet light-emitting diodes (UVLEDs).The influences of doped-Tb

concentration and charge compensation of Li

on the emission intensity were also investigated.The Sr
