Abstract

Low-dimensional organic-inorganic hybrid metal halides (OIMHs) have become an emerging class of light-emitting materials. Two zero-dimensional (0D) lead-free organic (EnrofloH₂)₄Mn₃X₁₂ (X = Cl, Br) has been reported in this work. Upon 338 and 340 nm excitation, (EnrofloH₂)₄Mn₃Cl₁₂·2Cl and (EnrofloH₂)₄Mn₃Br₁₂·2Br exhibit emission peaking at 460, 514 nm and 460, 520 nm respectively. It was noticed that the choice of the halide could profoundly govern the luminescent subjects (ENR or Mn²⁺) through the altered energy transfer. Different halogens could influence the rigidity of ENR organic cations by changing their stacking patterns and band gaps, thus manipulating their luminescent properties. The bandgap behaviors have been revealed by density functional theory calculations. Based on the results, the emission of both compounds come from organic cations (EnroﬂoH₂²⁺) and ⁴D-⁶A₁ transition of Mn²⁺ ions. The spectral interplay of these emission bands is governed by the temperature and the possibility of exchanging mechanisms between two emission centers.

不同卤素原子对有机阳离子刚性和能量转移的影响

低维有机-无机杂化金属卤化物(OIMHs)是一类新兴的发光材料。本文报道了两种零维无铅有机(EnrofloH2)4Mn3X12 (X = Cl, Br)。在338 nm和340 nm激发下，(EnrofloH2)4Mn3Cl12·2Cl和(EnrofloH2)4Mn3Br12·2Br分别在460、514 nm和460、520 nm处出现发射峰。注意到卤化物的选择可以通过改变能量转移来深刻地控制发光主体(ENR或Mn2+)。不同的卤素可以通过改变ENR有机阳离子的堆叠模式和带隙来影响其刚性，从而改变其发光性能。通过密度泛函理论计算揭示了带隙行为。结果表明，这两种化合物的发射来自有机阳离子(EnrofloH22+)和Mn2+离子的4D-6A1跃迁。这些发射带的光谱相互作用是由温度和两个发射中心之间交换机制的可能性决定的。

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.
