A series of Li2SrSiO4:xTb3+ (0.2%, 0.4%, 0.6%, 0.8%, 2%, 4%, and 6%) phosphors were prepared by conventional solid‐state reaction. It was found that this silicate phosphor has a wide excitation band at near‐ultraviolet region (230‐300 nm) due to spin‐allowed 4f8→4f75d1 transitions of Tb3+ ions, with the exact position dependent on the crystal field of the lattice. The cross‐relaxation process originating...
