“…36−38 Meanwhile, the increased intensity of the peaks at 70.0, 134.2, and 201.6 cm −1 indicates the enhancement of the outof-plane distortion in [MnX 6 ] 4− octahedron after Pb 2+ incorporating, which breaks the symmetry of the lattice. 31 This result supports the successful incorporating of Pb 2+ and is consistent with XRD results.…”

“…The Raman peak at 70.0 cm −1 is mainly derived from the out-of-phase oscillations of ionic slabs (without the contribution of central Cl/Br atoms) and the out-of-phase oscillations of the edge located Cs atoms. 31 The signals at 134.2 and 201.6 cm −1 are identified as the in-plane and out-plane motions of Mn and Cl/Br atoms while the combinations of in-plane vibrations of Cs and Cl/Br atoms are located at 103.0 and 159.7 cm −1 . 31 The results support the existence of Cs−Mn−Cl/Br.…”

“…As a result, the Pb 2+ -incorporated PA NCs skeleton is formed with a [Mn(Cl/Br) 4 (OH) 2 ] 4− − [Pb(Cl/Br) 4 (OH) 2 ] 4− −[Mn(Cl/Br) 4 (OH) 2 ] 4− consecutive chain structure by sharing corner X − (X = Cl, Br or OH) in Pb 2+ -incorporated PA NCs and the distance between [MnX 6 ] 4− −[MnX 6 ] 4− becomes shorter. 5,18,19,27,31 All peaks in the XRD patterns of pristine and Pb 2+incorporated PA NCs (Mn:Pb = 1:0.25) shown in Figure 1b can be indexed to CsMnCl 3 •2H 2 O (ICSD 24083) parameters with orthorhombic phase structures. The broad band located in the range of 2θ = 15−25°is characteristic of amorphous silica resulting from the hydrolysis of APTES.…”

“…30 Strong coupling between Pb and Mn induces effective energy transfer from Pb-based octahedron unit to luminescent Mn centers. 31 As a result, dual emission has been observed in Pb−Mn bimetallic perovskites consisting of a Mn 2+ -based d-to-d transition and a Pb 2+ -based excitonic emission. However, the existence of labile organic components is not ideal for practical applications.…”

Herein, we develop an effective approach for incorporating lead (Pb) ions into manganese (Mn) halide perovskite-analogue nanocrystals (PA NCs) of CsMn(Cl/Br)3·2H2O via room-temperature supersaturation recrystallization. Pb2+-incorporated Mn-PA NCs exhibit strong orange emission upon UV light illumination, a peak centered at 600 nm assigned to Mn2+ transition (4T1g → 6A1g) with a photoluminescence quantum yield (PLQY) of 41.8% compared to the pristine Mn-PA NCs with very weak PL (PLQY = 0.10%). The significant enhancement of PLQY is attributed to the formation of [Mn(Cl/Br)4(OH)2]4––[Pb(Cl/Br)4(OH)2]4––[Mn(Cl/Br)4(OH)2]4– chain network structure, in which Pb2+ effectively dilutes the Mn2+ concentration to reduce magnetic coupling between Mn2+ pairs to relax the spin and parity selection rules. In addition, excited energy can effectively transfer from the [Pb(Cl/Br)4(OH)2]4– unit to Mn2+ luminescence centers owing to the low activation energy. Pb2+-incorporated PA NCs also exhibit excellent stability. The combined strong PL and high stability make Pb2+-incorporated Mn-based PA NCs an excellent candidate for potential optronic applications.

Lead‐free metal halides are considered a new generation of optoelectronic materials due to their low toxicity, superior optoelectronic properties, ease of synthesis, structural diversity, and low cost. In particular, Mn2+‐based metal halides have earned intensive attention owing to their high emission quantum efficiency, rich physical properties (e.g., triboluminescence and stimuli‐responsivity), low cost, and toxicity. Due to the different coordination environments of Mn ions, Mn2+‐based metal halides can exhibit green, red, and near‐infrared emissions. This review summarizes the recent progress of Mn2+‐based metal halides in synthesis methods, emission mechanisms, photophysical properties, and representative applications in X‐ray scintillations, white light‐emitting diodes, optical anti‐counterfeiting technologies, and fluorescent sensors. Finally, the challenges and potential research directions toward developing Mn2+‐based metal halides are also predicted.

Zirconium silicate (ZrSiO3) perovskite is a promising material for various technological applications. The structural, electronic, and thermodynamic properties of ZrSiO3 perovskite are studied under different conditions, including pressure and layer configuration variations using density functional theory. The present investigation includes a thorough analysis of 2D perovskite derivatives derived from its basic 3D structure. The bulk and surface‐terminated silicon‐dominant SiO2 and zirconium‐dominant ZrO compounds are found to be mechanically stable with an anisotropy factor above 1. The calculated indirect‐bandgap values for the ZrO termination and SiO2 termination are found to be 2.585 and 1.639 eV, respectively. Moreover, the pore size of the SiO2‐terminated slab model of ZrSiO3 is calculated to be 105.39 μm and that for ZrO‐termination to be 129.30 μm. Thus, the material considered for the study can have potential applications in bone regeneration and tissue engineering. Further, the possibilities for modifying ZrSiO3 for uses in electrical devices, sensors, sustainable energy materials, and even biomedical applications like tissue engineering are intriguingly expanded by the present findings.
