Abstract
The invention discloses a Pb<2+>-doped ultraviolet long-afterglow luminescent material and a preparation method thereof. The luminescent material uses Sr2MgGe2O7 as a matrix and doping Pb<2+> ions as activation ions, wherein the Pb<2+> ions account for 0.05 to 2 mol% of the luminescent material. The preparation method comprises the following steps: mixing raw materials with a fluxing agent; carrying out low-temperature pre-burning at first; and then carrying out high-temperature sintering so as to obtain the ultraviolet long-afterglow luminescent material. The luminescent material prepared in the invention presents strong single-band ultraviolet long-afterglow luminescence performance. The peak of ultraviolet long-afterglow luminescence located at the position of 370 nm and afterglow time is as long as 12 h. Meanwhile, the material presents excellent photoexcitation luminescence performance. A sample having undergone high-energy ultraviolet pre-irradiation has obviously improved ultraviolet afterglow intensity after excitation by low-energy light (white light or near infrared light). The ultraviolet long-afterglow luminescent material has potential application value in fields like photochemical catalysis, disinfection and sterilization, counterfeiting prevention and medical photodynamic therapy.
