“…But the same phosphor when excited at λ ex = 467 nm exhibited weak emission at 701 nm due to the 5 D 0 → 7 F 4 transition, as shown in Figure 9. In Pb 5 (PO 4 ) 3 Br:Eu 3+ phosphor, as red emission at 614 nm is more than at 591 nm for both excitations ( λ ex = 395 and 467 nm), it can be concluded that the Eu 3+ does not occupy the inversion symmetry site [30–32]. The inset of Figures 8 and 9 shows that the maximum emission intensity is reached at 0.5 mol%, after which it decreases as the concentration of Eu 3+ activator ions increases.…”

“…The obtained CIE colour coordinates of Pb 5 (PO 4 ) 3 Br:Dy 3+ , Pb 5 (PO 4 ) 3 Br:DyEu 3+ and Pb 5 (PO 4 ) 3 Br:Tb 3+ phosphors are presented in Table 1. By mixing the three strong emissions at 480 nm from Pb 5 (PO 4 ) 3 Br:Dy 3+ phosphor, 547 nm from Pb 5 (PO 4 ) 3 Br:Tb 3+ phosphor and 395 nm from Pb 5 (PO 4 ) 3 Br:Eu 3+ phosphor defined by their colour coordinates, most of the parts of white shades within the triangle (shown by dark black lines) can be accessed, as shown in the Figure 11, and therefore the synthesised phosphor can be used for the development of white light‐emitting diodes [41–45].…”

This study describes the luminous properties of Pb5(PO4)3Br doped with RE3+ (RE = Dy3+, Eu3+ and Tb3+) synthesised using the solid‐state method. The synthesised phosphor was characterised using Fourier‐transform infrared, X‐ray diffraction, scanning electron microscopy and photoluminescence measurements. Dy3+‐doped Pb5(PO4)3Br phosphor exhibited blue and yellow emissions at 480 and 573 nm, respectively, on excitation at 388 nm. Eu3+‐doped Pb5(PO4)3Br phosphor exhibited orange and red emissions at 591 and 614 nm, respectively, on excitation at λex = 396 nm. Pb5(PO4)3Br:Tb3+ phosphor exhibited the strongest green emission at 547 nm on excitation at λex = 380 nm. Additionally, the effect of the concentration of rare‐earth ions on the emission intensity of Pb5(PO4)3Br:RE3+ (RE3+ = Dy3+, Eu3+ and Tb3+) phosphors was investigated.

The combustion procedure was used to synthesize La1.4Al22.6O36:Sm3+ phosphors. The X‐ray diffraction (XRD) patterns and morphological and photoluminescence properties were investigated. The XRD patterns consisted of a hexagonal crystal structure. At 405 nm, the maximum excitation intensity was obtained. Following 405 nm excitation, three different emission peaks at 573, 604, and 651 nm were seen. Concentration quenching occurred at 1.5 mol% Sm3+ ions. The Commission Internationale de l'éclairage coordinates for the La1.4Al22.6O36 phosphor with Sm3+ doping were 604 nm (x = 0.644, y = 0.355) falling in the red region. The findings implied that the prepared phosphor may be used to develop w‐light‐emitting diodes.

The CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor were prepared via combustion synthesis and studied by X‐ray diffraction (XRD), Fourier‐transform infrared (FTIR) analysis, scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDS), photoluminescence (PL) spectra and CIE coordinates. The phase formation of the obtained phosphor was analyzed by XRD and the result was confirmed by standard PDF Card No. 1539083. XRD data successfully indicated pure phase of CaAlBO4 phosphor. The crystal structure of CaAlBO4 phosphor is orthorhombic with space group Ccc2 (37). The SEM image of CaAlBO4 phosphor reveals an agglomerated morphology and non‐uniform particle size. The EDS image provides evidence of the elements present and the chemical makeup of the materials. Under the 350 nm excitation, the emission spectrum of Dy3+ activated CaAlBO4 phosphor consists of two main groups of characteristic peaks located at 484 and 577 nm which are ascribed to 4F9/2 → 6H15/2 and 4F9/2 → 6H13/2 transition of Dy3+ respectively. The PL emission spectra of CaAlBO4:Eu3+ phosphor shows characteristics bands observed around 591 and 613 nm, which corresponds to 5D0 → 7F1 and 5D0 → 7F2 transition of Eu3+ respectively, upon 395 nm excitation wavelength. The emission spectra of Sm3+ activated CaAlBO4 phosphor shows three characteristic bands observed at 565, 601 and 648 nm which emits yellow, orange and red color. The prominent emission peak at the wavelength 601 nm, which is attributed to 4G5/2 → 6H7/2 transition, displays an orange emission. The CIE color coordinates of CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor are calculated to be (0.631, 0.368), (0.674, 0.325) and (0.073, 0.185). As per the obtained results, CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor may be applicable in eco‐friendly lightning technology.
