The continuously growing significance of information security and authentication has put forward many new requirements and challenges for modern luminescent materials and anti-counterfeiting technologies. Recently, luminescent materials have attracted much attention in this field owing to their legibility, repeatability, multicolor, and multiple stimuli-responsive nature. In this work, the efficient multicolor and multimodal luminescence material CaCd2Ga2Ge3O12:Mn2+ was successfully designed and synthesized using the strategy of single-doped Mn2+ in a single matrix. Also, we combined the morphology, crystal structure, energy band calculation, luminescence properties, and trap analysis to study the optical data storage capacity of CaCd2Ga2Ge3O12:Mn2+. Interestingly, in the presence of the 254 nm UV lamp, the sample can exhibit a tunable emission color from bule to cyan to yellow by increasing the dopant concentration of Mn2+. Also, under the afterglow and thermoluminescence luminescence modes, it presented strong yellow emission centered at 558 nm. Based on the advantage of multiple tunable luminescence, samples were made into anti-counterfeiting ink and were used to print four optical devices through the screen printing technology. The results show that the material has excellent multicolor anti-counterfeiting properties under the three luminescence modes, which has contributed to the development of many kinds of luminescent anti-counterfeiting materials for security purposes.

“…Raman spectra show that the characteristic peaks of CoS at 338.0, 403.2, and 690.6 cm –1 arise in CoS/PNCFs and MnS–CoS/PNCFs, indicating the existence of CoS . It is not difficult to discover that there is a relative weaker peak at 656.3 cm –1 for MnS–CoS/PNCFs can be ascribed to be MnS species . Moreover, two characteristic peaks centered at 1332.8 cm –1 (D-band) and 1591.9 cm –1 (G-band) are observed of MnS–CoS/PNCFs, and the corresponding I D /I G value is 1.03, while the CoS/PNCFs is 1.01.…”

Seeking highly efficient, stable, and cost-effective bifunctional electrocatalysts of rechargeable Zn–air batteries (ZABs) is the top-priority for developing new generation portable electronic devices. For this, the rational and effective structural design, interface engineering, and electron recombination on electrocatalysts should be taken into account to reduce the reaction overpotential and expedite the kinetics of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Herein, we construct a MnCo-based metal organic framework-derived heterogeneous MnS–CoS nanocrystals, which are anchored on free-standing porous N-doped carbon fibers (PNCFs) by the in situ growth method and vulcanization process. Benefiting from the abundant vacancies and active sites, strong interfacial coupling as well as favorable conductivity, the MnS–CoS/PNCFs composite electrode delivers a mentionable oxygen electrocatalytic activity and stability with a half-wave potential of 0.81 V for ORR and an overpotential of 350 mV for OER in the alkaline medium. Of note, the flexible rechargeable ZAB using MnS–CoS/PNCFs as binder-free air cathode offers high power density of 86.7 mW cm–2, large specific capacity of 563 mA h g–1, and adapts to different bending degree of operation. In addition, the density functional theory calculation clarifies that the heterogeneous MnS–CoS nanocrystals reduces the reaction barrier and enhances the conductivity of the catalyst and the adsorption capacity of the intermediates during the ORR and OER process. This study opens up a new insight to the design of the self-supported air cathode for flexible electronic devices.

“…The capacity retention rate is close to 100% after 100 cycles at 0.3 A/g, and the capacity retention rate is as high as 104 mAh/g after 4000 cycles at 3 A/g (Figure 24e). Xu et al 108 designed a MnS/C nanosheet (MnS/C) cathode material by sulfidation of Mn-based organometallic precursors prepared in the laboratory. The electrochemical reaction mechanism was carefully demonstrated using in situ XRD, which indicated that MnS was converted to MnO x in the first cycle.…”

Hydroelectrochemical energy storage has the characteristics of high energy density, fast response time, low maintenance cost, flexible and convenient installation, etc., and is a hot development direction of future energy storage technology. Aqueous zinc-ion batteries (AZIBs) with neutral or near-neutral electrolytes have attracted much attention due to their advantages of safety, reliability, abundant resources, and environmental friendliness. Mn-based oxides are widely used as cathode materials for AZIBs due to their high theoretical specific capacity and low toxicity. However, Mn-based oxides face structural collapse during charge–discharge cycles, resulting in rapid capacity decay. This paper reviews the electrochemical characteristics of different Mn-based oxides as cathodes, the energy storage mechanism involved in the charging and discharging process of Mn-based AZIBs, and the advantages of Mn resources. At the same time, combined with the latest research progress, the existing problems and feasible improvement methods are pointed out, and the future development trend is prospected.
