“…Two peaks appear at 156.6 and 158.3 eV, which are derived from Y 3d 5/2 and Y 3d 3/2 , respectively. 39,40 Based on the XRD and XPS results, it is confirmed that Y 2 O 3 is composited with M-LVO. Remarkably, as described in Figure 1c, the V 2p 3/2 XPS spectra presents two peaks at 517.4 and 516.2 eV in the M-LVO-Y-2 sample.…”

Solid-state lithium metal battery (SSLMB) is regarded as a safer energy storage system compared to the liquid one. The performance of the SSLMB depends on the cathode performance and the side reactions derived from the interface of the cathode and the electrolyte, which becomes much severe at high temperatures. Herein, we carried out a facile spray-drying route to prepare a CNTs/LiV3O8/Y2O3 (M-LVO-Y) composite. The synthesized cathode material exhibits an outstanding Li+ storage performance with a high reversible capacity of 279.9 mA h g–1 at 0.05 A g–1, excellent power capability (182.5 mA h g–1 at 2 A g–1), and a long cycle lifespan of 500 cycles with a capacity retention of 66.5% at a current density of 1 A g–1. The fabricated rechargeable solid-state Li/M-LVO-Y-2 lithium metal battery (LMB) with a poly(ethylene oxide) (PEO)-based solid polymer electrolyte (SPE) achieves a high discharge capacity of 302.1 mA h g–1 at 0.05 A g–1 and a stable cycling performance with the highest capacity of 72.1% after 100 cycles at 0.2 A g–1 and 80 °C. The above battery performance demonstrates that SSLMBs with the CNTs/LiV3O8/Y2O3 cathode and the PEO-based SPE film can provide high energy density and are suitable for applying in a high-temperature environment.

“…The former peaks correspond to Eu 3+ 3d 5/2 and Eu 3+ 3d 3/2 , while the latter ones are ascribed to Eu 2+ 3d 5/2 and Eu 2+ 3d 3/2 . 35 The coexistence of Eu 2+ and Eu 3+ oxidation states is a characteristic spectral feature of europium-doped nanophosphors, providing more convincing evidence for the doping of Eu 3+ ions into the Y 2 O 3 lattice.…”

The direct, efficient, and controllable patterning of fluorescent materials on polymers is crucial for fundamental research and industrial application but very challenging. Herein, a DBD plasma method was used to deposit rare-earth-doped nanophosphors on the surface of polymeric substrates without thermal annealing steps, aiming to realize fluorescent patterning of thermally sensitive polymers through a simple and low-temperature process. Eu- and Tb-doped yttria (Y2O3) nanoparticles of different fluorescence properties were synthesized from rare-earth acetylacetonates to verify the feasibility of the process, followed by the formation of desirable fluorescent patterns on poly(vinylidene difluoride) (PVDF) membranes using relief printing to demonstrate the flexibility of this novel strategy. The results showed that crystalline rare-earth-doped Y2O3 nanophosphors were rapidly generated in plasma and can be deposited on the PVDF membranes to form fluorescent patterns without damaging the polymeric substrates. This method was further expanded to diverse substrates like polypropylene (PP), polyether sulfone (PES), and nylon, revealing the versatility of direct fluorescent patterning on thermally sensitive polymers. The efficient, flexible, and rapid plasma process combined with the desirable high-fluorescence patterns is expected to supply guidance for the design and fabrication of functional polymers.

“…Preparation of Y 2 O 3 : Eu 31 thin film Y 2 O 3 : Eu 3þ phosphor powders synthesised by combustion method 13 were pressed into discs (diameter W ¼ 10 mm, thickness h ¼ 2 mm) as target without further calcination. Quartz fibres were sequentially cleaned in distilled water and acetone and then dried in oven at 100uC for 24 h. Y 2 O 3 : Eu 3þ phosphor target was deposited onto quartz fibres by TG-250 EBE deposition vacuum system.…”

In this study, Eu 3þ doped Y 2 O 3 (Y 2 O 3 : Eu 3þ ) phosphor target was deposited on quartz fibre substrates by electron beam evaporation technology, and then the deposited fibres were annealed at different temperatures from 600 to 10008C. Particle shape was changed, and particle size of Y 2 O 3 : Eu 3þ was increased with the rise in annealing temperature. Crystallisation and luminescent intensity of the deposited films on quartz fibres were significantly improved by annealing treatment. The most effective crystallisation and the maximum luminescent efficiency of the thin films were obtained when the deposited fibres were treated at 10008C for 1 h. The luminescent property results indicated that the particle shape, particle size and crystallisation were the important factors affecting luminescent intensity of the deposited fibres.
