“…4,5 For example, the absence of concentration quenching was reported in Eu 3+and Tb 3+ -doped a-GdB 5 O 9 phosphors. [10][11][12] Massive efforts have been devoted to investigate the photoluminescent (PL) properties of phosphors such as REMB 9 O 16 :Tb 3+ , Ce 3+ (RE = La, Gd, and Y, M = Sr or Ba), 9 REBaB 9 O 16 :Eu 3+ (RE = La, Gd, and Y), 10,11,13,14 GdBaB 9 O 16 :RE (RE = Gd, Sm, Dy, Pr, and Nd), [15][16][17][18] LaBaB 9 O 16 :M (M = Bi 3+ , Mn 2+ ), 12 and EuBaB 9 O 16 . [8][9][10] Therefore, highly efficient blue, green, and red phosphors can be obtained by doping different activators, such as Eu 2+ , Mn 2+ and Eu 3+ , Tb 3+ .…”

Ba 6 (Bi 1Àx Eu x ) 9 B 79 O 138 (0 r x r 1): synergetic changing of the wavelength of Bi 3+ absorption and the red-to-orange emission ratio of Eu 3+ † Very recently, a novel barium bismuth borate Ba 6 Bi 9 B 79 O 138 (BBBO) was shown to be a new analogue of REBaB 9 O 16 (RE = rare earth), which is a family of excellent phosphor hosts, because it has two types of cationic positions suitable for bi-and tri-valent activators (or sensitizers). In this study, we prepared Eu 3+ -to-Bi 3+ substituted solid solutions Ba 6 (Bi 1Àx Eu x ) 9 B 79 O 138 (0 r x r 1) and performed a systematic UV-photoluminescence investigation. As anticipated, efficient energy transfer occurs in the whole series of compounds and the majority of the energy absorbed by Bi 3+ was transmitted to Eu 3+ , causing a great enhancement of Eu 3+ emission. More interestingly, the Eu 3+ -to-Bi 3+ substitution leads to a centrosymmetric-tononcentrosymmetric transition of the local coordination symmetry of the trivalent cations due to the size difference between Eu 3+ and Bi 3+ . This is observed in the synergetic changing of the wavelength of Bi 3+ 1 S 0 -3 P 1 absorption (excitation spectra) and the red-to-orange emission ratio (emission spectra) when changing x. BBBO is a new polyborate host with a freshly resolved structure whose interesting preliminary results suggest the further development of BBBO-based phosphors. † Electronic supplementary information (ESI) available: Unit cell parameters of Ba 6 (La 0.3Ày Bi y Eu 0.7 ) 9 B 79 O 138 (0 r y r 0.3), structural figures of Bi 3+ coordination in BBBO.

“…People obtained highly efficient blue, red, and green phosphors by doping respective activators, such as Eu 2þ , Mn 2þ and Eu 3þ , Tb 3þ [3e5]. Massive efforts have been devoted to investigate their photoluminescent (PL) properties, such as REMB 9 O 16 :Tb 3þ , Ce 3þ (RE ¼ La, Gd, and Y, M ¼ Sr or Ba) [2], REBaB 9 O 16 :Eu 3þ (RE ¼ La, Gd, and Y) [3,4,6,7], GdBa-B 9 O 16 :RE (RE ¼ Gd, Sm, Dy, Pr, Nd) [8e11], LaBaB 9 O 16 :M (M ¼ Bi 3þ , Mn 2þ ) [5], and EuBaB 9 O 16 [12,13]. These materials have potential applications in white light-emitting diodes (WLED) [13], tri-colour lamps [4,14], plasma display panels (PLD) under VUV excitation [6,15], and as well as laser materials [16].…”

CaAl2O4:Eu3+ (1 mol.%) co-doped with varying concentration of Gd 3+ (1, 2, 5, and 10 mol.%) were prepared by combustion synthesis method at 600• C and further annealed at 1000• C. All the compositions were investigated for their structural and photoluminescence properties. It was observed that both states of europium i.e. Eu 3+ and Eu 2+ were present and ratio of these states changes on heating at 1000• C. The materials synthesized at 600• C showed high intense peak around 440 nm due to presence of Eu 2+ and less intense peaks in the red region which were due to presence of Eu 3+ . On annealing the compounds at 1000• C, intensity of peak around 440 nm decreases and intensity of peaks in the red region increases significantly. The 5 D0 → 7 F3 transition due to Eu 3+ at 657 nm appears as the highest intensity peak. All co-doped samples annealed at 1000• C showed the higher intensity than the mono doped sample which is due to energy transfer from the Gd 3+ to Eu 3+ . The second rare-earth ion (Gd 3+ ) acts as sensitizer and enhances the photoluminescence intensity. The X-ray diffraction spectra reveal the monoclinic phase of CaAl2O4 in all the samples which showed that Eu 3+ and Gd 3+ do not change the crystalline structure of calcium aluminate.
