“…Dual color emission also exists when both coordination environments are present. , Triboluminescence , has been observed in noncentrosymmetric crystals, and pressure-induced photoluminescence was previously studied , in hybrid manganese halide systems. Extensive literature demonstrating high PLQYs has been reported on these materials, ,− but there has not been clear discussion of why certain compounds have better emission efficiencies. Oftentimes only materials with high PLQYs are reported, leaving out the materials with low PLQYs, which impacts the ability to establish structure–property relations.…”

Hybrid manganese halides have attracted widespread attention on account of their highly emissive optical properties. To understand the underlying structural factors that dictate the photoluminescence quantum yield (PLQY) of these materials, we report five new hybrid manganese bromides with the general formula AmMnBr4 [m = 1 or 2, A = dimethylammonium (DMA), 3methylpiperidinium (3-MP), 3-aminometylpiperidinium (3AMP), heptamethylenimine (HEP) and trimethylphenylammonium (TMPEA)]. By studying the crystal structures and optical properties of these materials and combining our results with the findings from previously reported analogs, we have found a direct correlation between Mn … Mn distance and the PLQY, where high PLQYs are associated with long Mn … Mn distances. This effect can be viewed as a manifestation of the concentration-quenching effect, except these are in stoichiometric compounds with precise interatomic distances, rather than random alloys. To gain better separation of the Mn centers and prevent energy transfer, a bulky singly-protonated cation that avoids H-bonding is ideal. We have demonstrated this principle in one of our newly reported material, (TMPEA)2MnBr4, where a PLQYs of 70.8 % for a powder sample and 98 % for a large single crystal sample is achieved. Our study reveals a generalized method for improving PLQYs in hybrid manganese bromides and is readily extended to designing all varieties of highly emissive hybrid materials.

“…At present, the research on Mn 2+ replacing Pb 2+ mainly focuses on organic–inorganic hybrid perovskites. These materials realized red or green emission with Mn 2+ participating in octahedral or tetrahedral coordination. − The reported organic–inorganic hybrid Mn-based perovskite demonstrated an unsatisfying PLQY (<60%) for red emission. , Even with some achievements, there is still a large gap between Mn-based and Pb-based halide perovskites in PLQY. In addition, organic–inorganic hybrid Mn-based materials also suffered poor thermal stability.…”

The toxicity of Pb and the instability of lead halide perovskites are the main obstacles to the practical application of lead-based nanocrystals (NCs). In this paper, all-inorganic Zn2+-doped lead-free perovskite (CsMn1–x Zn x Cl3) NCs were synthesized by a hot-injection method. Mn2+ ions were partially replaced by Zn2+ ions, and the energy transfer between Mn2+ was effectively suppressed. Because of this, excitons are more advantageously confined to the [MnCl6]4– octahedron. Target CsMn0.95Zn0.05Cl3 NCs were endowed with red emission at 654 nm with CIE coordinates of (0.70, 0.30) closing to the standard value of NTSC, and their photoluminescence quantum yield was increased to 77.1%, which is higher than those of Mn-based lead-free perovskites previously reported. Finally, a white light-emitting diode (LED) with adjustable emission from warm to cold white was realized by mixing Cs3MnBr5, CsMn0.95Zn0.05Cl3, and a blue phosphor on a 382 nm ultraviolet LED chip.

“…Subsequently, the core enhancement AgNP layer was integrated on top of the sensing chip. The as-prepared SERS paper chip was successfully applied for in situ detection of imidacloprid (IMI), showing ultra-high sensitivity with a detection limit of 0.02811 ng mL −1 , 2000 times more sensitive than other paper-based organic–inorganic manganese (II) halide hybrid sensors [ 87 ]. This multiple SERS enhancement paper chip holds great potential for screening a variety of contaminants.…”

Paper-based analytical devices (PADs) have emerged as a promising approach to point-of-care (POC) detection applications in biomedical and clinical diagnosis owing to their advantages, including cost-effectiveness, ease of use, and rapid responses as well as for being equipment-free, disposable, and user-friendly. However, the overall sensitivity of PADs still remains weak, posing a challenge for biosensing scientists exploiting them in clinical applications. This review comprehensively summarizes the current applicable potential of PADs, focusing on total signal-amplification strategies that have been applied widely in PADs involving colorimetry, luminescence, surface-enhanced Raman scattering, photoacoustic, photothermal, and photoelectrochemical methods as well as nucleic acid-mediated PAD modifications. The advances in signal-amplification strategies in terms of signal-enhancing principles, sensitivity, and time reactions are discussed in detail to provide an overview of these approaches to using PADs in biosensing applications. Furthermore, a comparison of these methods summarizes the potential for scientists to develop superior PADs. This review serves as a useful inside look at the current progress and prospective directions in using PADs for clinical diagnostics and provides a better source of reference for further investigations, as well as innovations, in the POC diagnostics field.
