“…As the Eu 3+ doping concentration is 9%, the phosphor shows the maximum emission intensity, the closest color coordinates with the standard red light as (0.646, 0.354) and excellent thermal stability as the emission intensity at 423 K remains 89% of that measured at room temperature. Various crystallographic sites for Eu 3+ provide suitable modification and optimization of the multi-site luminescence to realize high-quality applications of the novel phosphors [ 77 , 78 ].…”

The development of novel phosphor materials with excellent performance and modification of their photoluminescence to meet the higher requirements for applications are the essential research subjects for luminescent materials. Multi-site luminescent materials with crystallographic sites for the activator ions that broaden the tunable range of luminescent spectra and even enhance the luminescent performance have attracted significant attention in the pursuit of high-quality luminescence for white light-emitting diodes. Here, we summarize multi-site luminescence characteristics based on the different kinds of host and activator ions, introduce the identifications of multi-site activator ions via optical analysis, provide a structural analysis and theoretical calculation methods, and introduce the regulation strategies and advance applications of multi-site phosphors. The review reveals the relationship between crystal structure and luminescent properties and discusses future opportunities for multi-site phosphors. This will provide guidance for the design and development of luminescent materials or other materials science.

“…For example, structurally similar MBi2B2O7 (M = Ca, Sr, Ba) [8][9][10][11] borates form a family of prospective red-emitting phosphors. The photoluminescence properties of the M3Bi2(BO3)4:Eu 3+ (M = Sr, Ba) compounds were investigated in [12,13], and the crystal structure and photoluminescence of CaBi2B4O10:Eu 3+ phosphors were studied in [14]. Optical, structural, dielectric and photoluminescence properties of MO-Bi2O3-B2O3 (М = Ca, Sr, Ba) glasses were studied in [15][16][17][18][19][20][21][22][23].…”

The novel red-emitting BaBi2-xEuxB4O10 (x = 0.05, 0.1, 0.2, 0.25, 0.3, 0.4, 0.5, 0.6) phosphors were obtained by a crystallization from a glass. Distribution of the Eu3+ ions over cation sites were refined for x = 0.1, 0.3 and 0.4 from single-crystal X-ray diffraction data. Emission and excitation spectra of the Eu3+-doped BaBi2B4O10 phosphors were investigated for the first time, where it was shown that characteristic lines are attributed to the intraconfigurational 4f-4f transitions. The optimal concentration for the BaBi2-xEuxB4O10 phosphors is x = 0.4, after which a luminescence intensity decreases. The CIE chromaticity coordinates for the BaBi2B4O10:Eu3+ (x = 0.4) phosphor (0.65, 0.35) are close to the NTSC standard values (0.67, 0.33) for commercial red phosphor. The obtained results show that the BaBi2B4O10:Eu3+ phosphors are promising candidates for solid state lighting application.
