Luminescent properties of Na3Gd1−xEux(PO4)2 and energy transfer in these phosphors

Tuning the Bi3+-photoemission color over the entire visible region by manipulating secondary cations modulation in the ScVxP1−xO4:Bi3+ (0 ≤ x ≤ 1) solid solution

“…The emission-tunable approaches used for achieving the solid solutions have been widely described in the archival literatures, but strategies are usually focused on isostructural crystals that incorporate dopants like Eu 2+ [6], Ce 3+ [7], Mn 2+ [8], and Bi 3+ [9] ions whose spectral characteristics are very sensitive to the nature of their nearby chemical microenvironment, owing to the outer character of the emitting states. As a matter of comparison, the well-shielded 4f ions (e.g., Eu 3+ [10], Pr 3+ [11], Tb 3+ [12], Tm 3+ [13], Er 3+ [14][15] etc) and other 3d ions like Mn 4+ [16], and Cr 3+ [17]) usually exhibit their fixed spectral shape and positions, making the tunable-emission being less to realize in single ion doped solid solutions.…”

Crystal structure, tunable luminescence and energy transfer properties of Na3La(PO4)2:Tb3+,Eu3+phosphors

“…28 Meanwhile, there are a lot of evidence about the iso-structural of orthorhombic Na 3 Nd(PO 4 ) 2 with other sodium and rare-earth double orthophosphates Na 3 -RE(PO 4 ) 2 (RE ¼ Y, La-Er). 10,12,29,30 Here the crystal structure data of Na 3 Nd(PO 4 ) 2 is used as a starting model to rene the crystal structure.

Synthesis, characterization, and fluorescence properties of aniline‐g‐poly(styrene‐co‐maleic anhydride) and its lanthanide complexes

“…When excited at 293 nm, the AP/SMA polymer exhibited a broad emission band at 300–550 nm (maximum wavelength = 381 nm). As shown in Figure (b), several sharp lines in the range 300–500 nm were ascribed to the intraconfigurational 4f–4f transitions of the Eu(III) ions: 7 F 0 → 5 F 4 (303 nm), 5 H 6 (318 nm), 5 D 4 (362 nm), 5 G J (376 nm), 5 L 7 (383 nm), 5 L 6 (395 nm), and 5 D 3 (417 nm), respectively . We found that the excitation intensity at 395 nm was the highest in the excitation spectrum; this is very attractive for applications such as the red component of tricolor luminescence materials .…”
