NaLuF4:RE3+ (Dy3+, Tb3+, Eu3+, Tm3+): controllable morphology, multicolor light

“…6(b), upon excitation at 368 nm, the characteristic emission peaks of the Tb 3+ ions at 415 nm, 437 nm, 490 nm, 545 nm, 585 nm and 621 nm are detectable, corresponding to the 5 D 3 → 7 F 5 , 5 D 3 → 7 F 4 , 5 D 4 → 7 F 6 , 5 D 4 → 7 F 5 , 5 D 4 → 7 F 4 and 5 D 4 → 7 F 3 radiation transitions of Tb 3+ ions, respectively. 20,21…”

Ba3Lu(BO3)3:Ce3+,Tb3+/Mn2+: Dual-Functional Material for WLEDs and Optical Pressure Sensing

“…Because of the broad absorption and emission of Ce 3+ ions, they can typically be utilized as effective sensitizers to increase the luminance of Tb 3+ and Mn 2+ . , Tb 3+ ion generally showed green emission due to the distinctive 5 D 4 – 7 F 5 transition . The 4f–4f transition belongs to forbidden transitions.…”

“…6,7 Tb 3+ ion generally showed green emission due to the distinctive 5 D 4 − 7 F 5 transition. 8 The 4f−4f transition belongs to forbidden transitions. Hence, the absorption of Tb 3+ is typically quite weak.…”

Synthesis Design and Properties of Ca5(BO3)3F: Bi3+/Eu3+: Insight into Luminescence, Temperature, and Pressure Sensing

“…According to the reports, the fibrous material offers several advantages, including a large specific surface area, a high length-diameter ratio, a significant surface-volume ratio, as well as favorable mechanical properties. 5 Because of their high surface-to-volume ratio, nanofibers have potential applications in biosensing, cell imaging, and drug delivery, 6 while the spherical particle is conducive to the construction of a compact phosphor layer through the close arrangement of the spheres, minimizing the light scattering on the surface of the particles, thus enhancing the luminescence performance. 7 Consequently, it is essential to explore a variety of morphologies.…”
