Shortwave Ultraviolet Persistent Luminescence of SrMgSiO: Pr.

Currently, extensive research activities are devoted to developing persistent phosphors which extend beyond the visible range. In some emerging applications, long-lasting emission of high-energy photons is required; however, suitable materials for the shortwave ultraviolet (UV-C) band are extremely limited. This study reports a novel SrMgSiO phosphor doped with Pr ions, which exhibits UV-C persistent luminescence with maximum intensity at 243 nm.
