A Highly Enhanced Photoluminescence of Eu3+-Activated CaTiO3 Phosphors via Selective A-Site and B-Site Cation Substitutions (Sr2+ and Sn4+)

  • 12 Accesses


Sr2+ and Sn4+ doped CaTiO3:Eu3+ phosphors were prepared by a high temperature solid-state method. X-ray diffraction characterization shows that the sample calcined at 1200°C is pure and has an orthorhombic crystal lattice. Photoluminescence (PL) measurement shows that CaTiO3:Eu3+ has five excitation peaks at 363 nm, 381 nm, 398 nm, 418 nm, and 466 nm, respectively corresponding to the transitions 7F0 → 5D4, 7F0 → 5L7, 7F0 → 5L6, 7F0 → 5D3 and 7F0 → 5D2 of Eu3+. The main emission peaks of CaTiO3:Eu3+ at 592 nm and 613 nm are ascribed to the 5D0 → 7FJ (J = 1, 2) transitions of Eu3+. In addition, PL emissions at 592 nm and 613 nm of CaTiO3:Eu3+ phosphors are enhanced remarkably through A-site substitution of Ca2+ with Sr2+ or B-site substitution of Ti4+ with Sn4+. Noticeably, the emission intensity of Ca(Ti,Sn)O3:Eu3+ is nearly three times higher than that of CaTiO3:Eu3+. The reason is that substitution of Ti4+ with Sn4+ induces a large lattice distortion, which promotes the 5D0 → 7F2 transition probability and thus enhances the emissions at 613 nm. It is also found that Sr2+ substitution narrows the optical bandgaps of CaTiO3:Eu3+ , while Sn4+ substitution widens them. In addition, chromatic purity of the phosphors shows a remarkable dependence on the asymmetric ratio.
