To date, non-contact luminescence thermometry methods based on fluorescence intensity ratio (FIR) technology have been studied extensively. However, designing phosphors with high relative sensitivity (Sr) has become a research hotspot. In this work, Eu3+ single-doped Ca2Sb2O7:Eu3+ Sr value for dual-emitting-center are developed and proposed. The anti-thermal quenching behavior of originating from the energy transfer (ET) host → is found proved in designed phosphors. Interestingly, adjustable...
With admirable luminescence performance and a cheap price, non-rare-earth-based oxide red phosphors are potential competitor of rare-earth-doped for warm white LEDs (WLEDs). Herein, novel double-perovskite Ba2GdSbO6:Mn4+ phosphor, demonstrating strong emission ascribed to spin-forbidden Mn4+:2Eg → 4A2g transition in the region 620-750 nm, has been synthesized via solid-state reaction route. The microstructure properties investigated detail. concentration quenching mechanism thermal stability...
(a) Transmission electron microscopy images and (b) normalized up-conversion emission spectra of transparent Er<sup>3+</sup>-doped NaYb<sub>2</sub>F<sub>7</sub> GC680 at various temperatures from 300 to 773 K.
Owing to its low-cost and satisfactory luminescent-emission performance in warm white light-emitting diodes (w-LEDs), the non-rare-earth Mn4+-activated red phosphor has become a promising competitor of commercial rare-earth doped phosphor. In this study, series novel red-light emitting phosphors based on Ca2YSbO6:Mn4+ have been developed successfully by conventional solid-state reaction. The structural luminescent properties these are systematically investigated. as-prepared product exhibits...
Abstract Yb/Er doped hexagonal β‐NaLnF 4 (Ln = Gd, Y, Lu) are regarded as the most efficient green upconversion (UC) materials. Unfortunately, is quite difficult to grow monocrystal owing cubic‐to‐hexagonal phase transition during cooling. As an alternative, herein a nanocrystallization controllable strategy synthesize monodisperse whole‐family (from NaLaF NaLuF ) embedded bulky glass ceramics reported. A series of structural and spectroscopic characterizations indicate that Na content Al/Si...
In the past few decades, efficient photon upconversion (anti-Stokes) luminescence has been extensively studied and is almost exclusively restricted to lanthanide (Ln<sup>3+</sup>) doped fluorophores.
Optical thermometers usually make use of the fluorescence intensity ratio two thermally coupled energy levels, with relative sensitivity constrained by limited gap. Here we develop a strategy using upconversion (UC) emissions originating from multiplets opposite temperature dependences to achieve higher sensitivity. We show that UC emissions, ³F(2,3) and ¹G₄, Tm³⁺ in β-NaYF₄:20%Yb³⁺, 0.5%Tm³⁺/NaYF₄:1%Pr³⁺ core-shell nanoparticles under 980 nm laser excitation exhibits high between 350 510 K,...
Abstract Due to its suitable working voltage and high theoretical storage capacity, antimony is considered a promising negative electrode material for lithium‐ion batteries (LIBs) has attracted widespread attention. The volume effect during cycling, however, will cause the anode undergo severe structural collapse rapid decrease in capacity. Here, general situ self‐template‐assisted strategy proposed rational design preparation of series MSb (M = Ni, Co, or Fe) nanocomposites with MNC...
Lithium-ion batteries (LIBs) and potassium-ion (KIBs) have broad application prospects in the fields of small/medium-sized electronic products large-scale energy storage. However, fast low reversible capacity decay, poor rate capacity, slow charge storage kinetics severely affect their applications. In this work, a Bi2Se3@C rod-like architecture was synthesized through an situ selenization method using metal–organic frameworks as precursor. The micro/nanoporous carbon structure not only...

Non-contact optical thermometry using rare-earth materials has attracted a lot of attention due to its realization non-invasive and real-time temperature determination.
Cr3+-doped Bi2Ga4O9-Bi2Al4O9 solid-solution (SS) phosphors were fabricated to explore their possible application in fluorescence lifetime-based temperature sensing. The present samples exhibited E2→A24 R-line emissions associated with T24→A24 phonon sideband of Cr3+ the wavelength range 600-850 nm upon excitation visible light. Through modifying Al/Ga ratio SS hosts, crystal field was easily tuned from intermediate strong, being beneficial modulate an energy gap between E2 and T24 thermally...
