Abstract
Abstract The Sr1.99-xBi0.01CeO4:xRE3+ (RE3+ = Dy3+, Sm3+ and Eu3+, x = 0 and 0.03) single, co-doped and tri-doped phosphors synthesized by solid state reaction technique and their structure analysed by X-ray powder diffraction technique (XRD). The results shows that the Dy3+,Sm3+, Eu3+, Dy3+/Sm3+, Sm3+/Eu3+, Dy3+/Eu3+, and Dy3+/Sm3+/Eu3+ ions are effectively studded into the host lattice site without changing the structure of the host. The luminescence and energy transfer properties of the Sr1.99-xBi0.01CeO4:xRE3+ have been investigated for single, co-doped and tri-doped phosphors under each of the 387 nm (Dy3+: 6H15/2 → 4I13/2), 409 nm (Sm3+: 6H5/2 → 6P3/2) and 466 nm (Eu3+: 7F0→5L6) excitation levels wherein the mean emission values reportedly seem to be 572, 651 and 615 nm respectively. The chromaticity coordinates and decay time of the synthesized materials are also examined.
