摘要：
A series of Tb3+ doped Sr2La8(SiO4)(6)O-2 phosphors were successfully synthesized via sol-gel method. The formations of sol-gel phosphors were confirmed using powder X-ray diffraction studies. The emission intensity shows the 544 nm (D-5(4) -> F-7(5)) maximum that was obtained for the prepared samples using the 233 nm excitation. Luminescence quenching was not observed for the prepared series of the Tb3+. doped Sr2La8(SiO4)(6)O-2 phosphors. The addition of the Tb3+ concentration greatly improved the photoluminescent properties of the present phosphors. (C) 2018 Elsevier GmbH. All rights reserved.
