摘要

铅基卤化物具有卓越的光电和磁性能，是一类极有前途的材料。然而，铅基卤化物的高毒性和不稳定性对其实际应用产生了不利影响。为了解决这些问题，我们研究了一种无铅一维锰（Mn）基有机无机卤化物 (TZI)MnCl3（TZI = 噻唑烷-3-鎓）。红色发光的 (TZI)MnCl3 在波长为 373 纳米和 446 纳米的光激发下，光致发光量子产率分别高达 46.4% 和 30.6%。此外，(TZI)氯化锰在各种条件下都表现出很高的稳定性，突显了其在光电应用方面的潜力。

Synthesis and stability of one-dimensional red-emitting manganese-based Organic–inorganic halide

Pb-based halides are a highly promising class of materials due to their exceptional optoelectronic and magnetic properties. However, lead-based halides’ high toxicity and instability have detrimentally affected their actual applications. To address these issues, we investigated a lead-free one-dimensional manganese (Mn)-based organic–inorganic halide (TZI)MnCl₃ (TZI = thiazolidin-3-ium). The red-emitting (TZI)MnCl₃ demonstrated photoluminescence quantum yields of up to 46.4 % and 30.6 % when excited by light at wavelengths of 373 nm and 446 nm, respectively. Furthermore, (TZI)MnCl₃ exhibited high stability under various conditions, highlighting its potential for optoelectronic applications.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
