Developing green perovskite light-emitting diodes (PeLEDs) with a high external quantum efficiency (EQE) and low roll-off at brightness remains critical challenge. Nanostructured emitter-based devices have shown but restricted ascending luminance current densities, while based on large-sized crystals exhibit face great challenges to efficiency. Herein, we develop an all-inorganic device architecture combined utilizing tens-of-nanometers-sized CsPbBr3 (TNS-CsPbBr3) emitters in...
Er(3+) doped Y2O3 and Nb2O5 modified germanate glasses with different concentrations were prepared. J-O intensity parameters computed to estimate the structural changes due additions of Nb2O5. The main mid-infrared spectroscopic features investigated. To shed light on observed radiative behavior, 975 nm 1.53 μm emission spectra along their decay lifetimes also discussed. Moreover, energy transfer processes (4)I11/2 (4)I13/2 level quantitatively analyzed. In view experimental lifetimes,...
The practical application of the metallic lithium anode is suppressed by highly unstable interface between electrolytes and metal during process plating/stripping. A perfect solid electrolyte interphase (SEI) can inhibit detrimental parasitic reactions, thereby improving cycling performance anode. In this work, a high-purity difluorobis(oxalato) phosphate (LiDFOP) synthesized an outstanding organic–inorganic hybrid SEI obtained in ether-based for first time induced LiDFOP. preferential...
A novel tricolor phosphor-in-glass film (PiGF) with high luminous efficiency (LE) and color rendering index (Ra) was designed fabricated by optimizing the glass layer thickness, phosphor ratio, structure, sintering process.
This work reports the mid-infrared emission properties around 2 μm in Ho 3+ /Yb codoped germanate glasses.The glass not only possesses good chemical durability and thermal stability but also has high midinfrared transmittance (90%).In addition, considerably low OH -content (20.45 ppm) large spontaneous transition probability (103.38 s -1 ) corresponding to : 5 I 7 → 8 transition.Moreover, measured lifetime of level is as 7.68 ms, quantum efficiency at can reach 79.4%.The energy transfer...
Iodine-based perovskite light-emitting diodes (PeLEDs) utilizing zinc oxide (ZnO) films as electron-transporting layers (ETLs) show excellent efficiency and stability. However, the poor understanding of reaction between bromine-based perovskites ZnO hinders preparation high-quality on films. Here, we demonstrate an in situ interfacial amidation one amino group formamidinium bromide (FABr) sol–gel film, leaving unreacted groups to form amino-rich ZnO/perovskite interface. The density groups,...
Abstract The development of all‐inorganic lead‐free Cs 3 Cu 2 I 5 perovskite materials has garnered significant attention due to their non‐toxic nature and unique optoelectronic properties, particularly in the field X‐ray detection. However, stability perovskites remains a major concern for optical applications. In this study, highly stable ‐in‐glass composite (Cs @Borosilicate) is fabricated by spark plasma sintering (SPS), rapid low‐temperature process. @Borosilicate exhibits strong...
The energy transfer mechanism between Ho(3+) and Er(3+) ions has been investigated in germanosilicate glass excited by 980 nm laser diode. A rate equation model was developed to demonstrate the from ions, quantitatively. Energy efficiency Er(3+):(4)I13/2 Ho(3+):(5)I7 level can reach as high 75%. Such a attributed excellent matching of host phonon with gap levels. In addition, microparameter (CDA) estimated (4.16 ± 0.03) × 10(-40) cm(6)·s(-1) via host-assisted spectral overlap function,...
Cu2+ is an essential trace element for humans and animals, the precise detection of can help diagnose many diseases. However, current technology still needs to be improved in terms biocompatibility material, penetration excitation source, limit. In this paper, polyacrylic acid (PAA) capped NaYF4:Yb3+/Er3+@NaYF4 core–shell nanoparticles (NPs) with a particle size about 22.5 nm proposed.
