Tuning the Bi³⁺-photoemission color over the entire visible region by manipulating secondary cations modulation in the ScV_xP_1−xO₄:Bi³⁺ (0 ≤ x ≤ 1) solid solution

Abstract

Manipulating the secondary cation ratio in the ScVxP1−xO4:Bi3+ solid solution allows tuning of the excitation tail from 340 to 425 nm and the corresponding emission maximum from 455 to 641 nm, without significant reabsorption.

Luminescence in external dopant-free scandium-phosphorus vanadate solid solution: a spectroscopic and theoretical investigation

“…4b, curve 1), the variation tendency of E g is on the whole the same. Besides, the VCA simulation matches well the tendency reported in our previous work 26…”

“…2c(i), which are evaluated by the Bragg equation of 2d sin y = l (where l is the X-ray wavelength, and y is the diffraction angle). 25,26 All the raw XRD data are refined further using the Rietveld refining method, and four typical refined XRD patterns are shown in Fig. 3, i.e., the Sc(P x ,V 1Àx )O 4 (x = 0.2 ( Fig.…”

“…1a, are relatively simple, containing only one type of Sc and B site coordinated respectively by eight and four oxygen atoms, but the Sc-O bonds have two different lengths. 26,[31][32][33] Since ScVO 4 and ScPO 4 are all crystallized in a tetragonal space group of I4 1 /amd and the [ScO 8 ] and [BO 4 ] polyhedral structures share the same oxygen atoms and/or oxygen edges, the formation of the Sc(P x ,V 1Àx )O 4 (0 r x r 1) solid solutions becomes, therefore, possible. According to the ICSD files no.…”

Recent advances and prospects of persistent luminescent materials as inner secondary self-luminous light source for photocatalytic applications

“…Bandlike persistent luminescence can also be achieved in MPLs doped with ns 2 cations like Bi 3+ [141,149,234,[257][258][259][260][261][262][263][264][265][266][267][268][269] or Pb 2+ ion [270][271][272][273] (Table 4). Unlike the Mn 4+ and Cr 3+ ions yet similar to the Eu 2+ , Ce 3+ , and Mn 2+ ions, single Bi 3+ ion, depending on different crystal hosts, can exhibit the fluorescence broadly spanning from UV, blue, yellow and to reddish/red [45,[274][275][276][277][278][279][280][281][282][283][284][285].…”

Achievement of narrow-band blue-emitting phosphors KScSr1−yCaySi2O7:Bi3+ by the migration of luminescence centers

“…Absorption takes place from 1 S 0 fundamental state to 3 P 1 , 3 P 2 and 1 P 1 excited states. 12,13 Beneting from its naked 6s and 6p orbits, Bi 3+ has a broadly adjustable luminescence spectrum, affected by different crystal eld environments, which opens up great possibilities for ion regulation. For instance, Peng's team reported CaMoO 4 :Bi 3+ phosphors, half peak width is about 200 nm, mainly studies the cationic alternative implementation color adjustable launch in 2014.…”
