“…[ 40 ] As shown in Figure 5d, the B 1 s spectra peaking at 192.6 eV correspond to B 2 O 3 , [ 41 ] whereas peaking at 191.8 eV results from lithium metaborate. [ 42 ] The Li 1 s spectrum shows a sole peak at binding energy of 55.6 eV (Figure 5e), which is consistent with the FA.…”

Electron injection plays a key role in electron–photon conversion properties of inverted UV–visible organic light‐emitting diodes (OLEDs). Herein, facilely prepared solution‐processed lithium carbonate (Li2CO3) formic acid and boric acid solutions for tailoring electron injection in inverted near‐UV (NUV) OLEDs are studied. Superior film morphology and exceptional electronic properties of spin‐coated Li2CO3 films are examined by atomic force microscopy, X‐ray/ultraviolet photoelectron spectroscopy, current–voltage curves, and impedance spectroscopy. Efficient inverted NUV OLEDs are assembled using wide‐bandgap molecule of 2‐(4‐biphenyl)‐5‐(4‐tert‐butylphenyl)‐1,3,4‐oxadiazole as emissive layer, showing maximum radiance of 5.24 mW cm−2 (2.28 mW cm−2) and external quantum efficiency of 2.47% (2.17%) with an optimal Li2CO3 formic acid of 3 mg ml−1 (Li2CO3 boric acid of 7 mg ml−1) as electron injection tailoring. The NUV emission shows electroluminescence peaks of 404–406 nm and full width at half maximum of 52–56 nm. The results provide some feasible approaches for enhancing the performance of organic electronic devices, which require strong electron injection/extraction and accelerate industrialization.

“…3, the B 1s spectra of the post-treated sample aer 1 h clearly showed the formation of LiBO 2 and the absence of the NbB 2 signal. [37][38][39] On the basis of these results, it can be safely concluded that Nb 2 O 5 reacts with the molten LiBH 4 following eqn (2) in the isothermal treatment.…”

“…The survey spectrum shows that the sample consists of B, C, O, Co, and Ni (Figure S1a in the Supporting Information). As can be seen from Figure 1c, the peak with the binding energy of 191.6 eV for the B 1s level can be assigned to the BO 2 − group, 23 not BO 3 3− with high binding energy (192.8 eV), 24,25 indicating that the "B−O" exists as BO 2…”

Enhanced Structural Stability of Nickel–Cobalt Hydroxide via Intrinsic Pillar Effect of Metaborate for High-Power and Long-Life Supercapacitor Electrodes

Layered α-Ni(OH) and its derivative bimetallic hydroxides (e.g., α-(Ni/Co)(OH)) have attracted much attention due to their high specific capacitance, although their insufficient cycling stability has blocked their wide application in various technologies. In this work, we demonstrate that the cycling performance of α-(Ni/Co)(OH) can be obviously enhanced via the intrinsic pillar effect of metaborate. Combining the high porosity feature of the metaborate stabilized α-(Ni/Co)(OH) and the improved electronic conductivity offered by graphene substrate, the average capacitance fading rate of the metaborate stabilized α-(Ni/Co)(OH) is only ∼0.0017% per cycle within 10 000 cycles at the current density of 5 A g. The rate performance is excellent over a wide temperature range from -20 to 40 °C. We believe that the enhancements should mainly be ascribed to the excellent structural stability offered by the metaborate pillars, and the detailed mechanism is discussed.
