Reversible human-temperature-responsive luminescence switching in a Mn(ii)-based metal halide

Abstract

The flexibility afforded by the modular structure confers fruitful unique properties to the organic-inorganic hybrid metal halides (OIMHs). Typically, stimuli-responsive materials have wide applications in thermal imaging, thermometer, and anti-counterfeiting....

Two Organic–Inorganic Manganese(II) Halide Hybrids Showing Compelling Photo- and Mechanoluminescence as well as Rewritable Anticounterfeiting Printing

“…Lei reported a family of OIMHs with reversible off–on switching luminescence, which can be used in water-jet rewritable printing, anticounterfeiting, and encryption and decryption . Although significant progress has been made, − rewritable anticounterfeiting printing based on OIMHs as an emitter is still in its infancy and deserves to be thoroughly explored.…”

Dielectric/SHG/PL triple-channel properties in chiral spirocyclic organic–inorganic hybrids

“…The PL properties come from the d–d transition of tetrahedral coordinated Mn 2+ , corresponding to the 3d 5 electronic transition of Mn 2+ from the excited state 4 T 1 to the ground state 6 A 1 . 46,54 The CIE chromaticity coordinates of ( R -HASD) 2 MnBr 4 and ( S -HASD) 2 MnBr 4 are (0.206, 0.697) and (0.211, 0.695), respectively, which are located in the green area shown in Fig. 5f.…”

Multifunctional dielectric/optical response with broadband white light emission in a hybrid stannic halide crystal

“…39,40 Subsequently, many dielectric multifunctional materials emitting various colors, such as red, green, yellow, blue, and others, were explored, significantly enriching the development of fluorescent dielectric multifunctional materials. 38,[41][42][43][44][45] Luo et al also reported white light dielectric responsive lead-based materials, which have a warm white light a color temperature of 4423 K and have high color rendering index (CRI) of up to 86. 28 Despite these great advances, the single material simultaneously equipped with a dual channel optical/electrical response of dielectric switching response and intrinsic broadband white-light emission has been very rare and an ongoing challenge.…”
