Luminescence properties of Ba2NaNb5O15 crystals activated with Sm3+, Eu3+, Tb3+ or Dy3+ ions

Impedance spectroscopy study of Na2SmV5O15 ceramics

“…They also have the ability to act as intercalation, ion-exchange, magnetism, cathode, and nonlinear optical (NLO) materials [1][2][3][4][5][6][7]. In vanadates, vanadium has been found in three-, four-, five-, and six-coordinate environments.…”

Growth and Characterization of Centimeter‐Sized Ba2LaFeNb4O15 Crystals from High‐Temperature Solution under a Controlled Atmosphere

“…Since 2006, the optical properties of BNN single crystals (with sizes up to 2 ϫ 2 ϫ 3 mm 3 ) activated with trivalent lanthanide ions and grown in Na 2 B 4 O 7 flux have been examined. [34][35][36] Structural features play a crucial role in the physical properties of TTB niobates, especially their dielectric properties. In the paraelectric state, the TTB structure is expected to be centrosymmetric with space group P4/mbm.…”

Luminescence properties of novel Sm3+, Dy3+ doped LaMoBO6 phosphors

“…Because the 4f electrons of RE ions are shielded by the outer 5s and 5p electrons, the intra-4f emission spectra of RE ions are characterized by narrow lines with high color purity. The emission of Sm 3+ is situated in the orange spectral region and consists of transitions from the excited 4 G 5/2 level to the ground state 6 H 5/2 and higher levels 6 H J (J > 5/2) [10][11][12]. The luminescence lines of Dy 3+ are in the 480 nm region (blue) due to the 4 F 9/2 → 6 H 15/2 transition, and in the 570 nm region (yellow) due to the 4 F 9/2 → 6 H 13/2 transition.…”

“…The color of the luminescence is close to white if a suitable ratio of B/Y obtained. Therefore, Dy 3+ doped materials may be potential two primary color phosphors [12,14,15].…”
