title: Synthesis and photoluminescence characteristics of Sm3+-doped Bi4Si3O12red-emitting phosphor.
abstract: A series of novel red-emitting Sm3+-doped bismuth silicate phosphors, Bi4Si3O12:xSm3+(0.01 ≤ x ≤ 0.06), were prepared via the sol-gel route. The phase of the synthesized samples calcinated at 800 °C is isostructural with Bi4Si3O12according to X-ray diffraction results. Under excitation with 405 nm light, some typical peaks of Sm3+ions centered at 566, 609, 655 and 715 nm are found in the emission spectra of the Sm3+-doped Bi4Si3O12phosphors. The strongest peak located at 609 nm is due to4G5/2-6H7/2transition of Sm3+. The luminescence intensity reaches its maximum value when the Sm3+ion content is 4 mol%. The results suggest that Bi4Si3O12:Sm3+may be a potential red phosphor for white light-emitting diodes. Copyright © 2016 John Wiley & Sons, Ltd.
