“…Fibers and fabrics with bright luminescence seem extremely interesting, and we can even imagine the luminescence signals to be sensed and probed. Most lanthanide elements, such as europium (Eu 3+ ) and terbium (Tb 3+ ), have unique luminescence performance, a high color purity, and a stable emission wavelength [ 1 , 2 , 3 , 4 , 5 , 6 ], so they are used in lasers and luminescent materials, as well as biomedical applications [ 7 , 8 , 9 , 10 , 11 , 12 ]. However, it is a fact that they emit relatively weak luminescence, so lanthanide ions (Ln 3+ ) have to be coordinated with organic ligands to form luminescence complexes to obtain better fluorescent properties [ 13 , 14 , 15 , 16 , 17 ].…”

With the growing needs for flexible fluorescence emission materials, emission fibers and related wearable fabrics with bright emission properties have become key factors for wearable applications. In this article, novel cuboid-like crystals of Eu3+ complexes were generated. Except for light-energy-harvesting ligands of thenoyltrifluoroacetone (TTA) and 1,10-phenanthroline hydrate (Phen), the crystal structures were adjusted by other functional amphiphilic molecules. Not only does ETPC-SA, adjusted by stearic acid, have a regular cuboid-like crystal with a size of about 2 μm size, but it also generates the best photon emission property, with a fluorescence quantum yield of 98.4% fluorescence quantum yield in this report. Furthermore, we succeeded in producing novel fluorescent fibers by mini-twin-screw extrusion, and it was easy to form bright red fabrics, which are equipped with strong fluorescence intensity, flexibility, and a smooth hand feeling, with the normal fabricating method in our work. It is worth noting that ETPC-HQ fibers, which carry a crystal complex adjusted by hydroquinone, possess the lowest quantum yield but have the longest average fluorescence lifetime of 1259 µs. This result means that a low-density polyethylene (LDPE) matrix could make excited electrons stand in the excited state for a relatively long time when adjusted by hydroquinone, so as to increase the afterglow property of fluorescent fibers.

“…Figure1cand TableS3, it contains three cation sites, including octahedral Al/MgO 6 , tetrahedral Al/MgO 4 , and pentahedral BaO 6 sites 30,31. Figure1dpresents the electronic structure of the BAM sample, which shows an indirect band gap of 4.457 eV, and according to the density of states (DOS), the conduction band is due to the cation levels, whereas the valence band is due to the O 2p orbitals.32−34 Moreover, the SEM image (Figure1e) indicates that the BAM particles are hexagonal in shape, and slight agglomeration can be observed due to the solid-state reaction at high temperatures.35−37 Based on the elemental distribution in Figure1f, all the elements were homogeneously composited in the BAM particles.…”

A bifunctional luminescent whitening and luminescent sensing composite material, BaMgAl 12 O 17 :Eu 2+ /polydimethylsiloxane (BAM/PDMS), that utilizes natural sunlight and mechanical energy is presented. By increasing the Eu 2+ content, the photoluminescence (PL) excitation spectrum of the material shows a maximum redshift of 23 nm due to 5d level splitting of Eu 2+ , resulting in more spectral overlap with sunlight and an excellent PL whitening effect. Meanwhile, the self-recoverable mechanoluminescence (ML) of the material can be easily excited under mechanical stimuli due to contact electrification, exhibiting a unique stress sensing effect. Based on the unique features of PL whitening and ML sensing, the material is applied to model cars through a spray process, and the results demonstrate that the bifunctional BAM/PDMS material shows promising applications in automobile decoration.

An aluminate is a compound containing an oxyanion of aluminum. Many aluminates are found in nature. A large number of phosphors that are used in various applications, such as scintillation detectors, optical thermometry, longlasting phosphorescence, solid-state lighting, solid-state lasers, upconversion, bioimaging, and plasma display panels, are based on aluminate formulae. This review focuses on the synthesis and characteristics of such phosphors. The conventional as well as novel methods of synthesizing these phosphors are reviewed. The emphasis on commercially important aluminate phosphors is discussed.
