Photoluminescent ionic metal halides based on s2 typed ions and aprotic ionic liquid cations

Nearly one-fold enhancement in photoluminescence quantum yield for isostructural zero-dimensional hybrid antimony(iii) bromides by supramolecular interaction adjustments

“…Recently, zero-dimensional (0D) organic–inorganic metal halides (OIMHs) have fascinated the research community due to their diversified structures, and tunable and strong photoluminescence (PL). 1–6 0D OIMHs based on n s 2 ions (mainly Ge 2+ , Pb 2+ , Sn 2+ , Sb 3+ , Bi 3+ , and Te 4+ ) exhibit PL of self-trapped excitons (STEs) due to their soft lattices and strong electron–phonon coupling. 7–17 Benefitting from the relatively low toxicity and valence stability of Sb 3+ ions, antimony( iii ) based 0D OIMHs have become a research hotspot with promising applications.…”

Photophysical properties of ammonium, pyrrolidinium, piperidinium, imidazolium, and pyridinium as a guide to prepare ionic-organic hybrid materials

“…ILCs couple either with halometal [18][19][20] or hybrid organic inorganic perovskites (HOIPs) [12,21,22]. The presence of ILCs influences the packing density in the structure.…”

“…In contrast to all-inorganic materials that require high temperature for synthesis through the solid-state method, organic-inorganic hybrid materials can be synthesized via simpler methods such as solvothermal [ 12 , 13 , 14 ], hydrothermal [ 15 , 16 ], or diffusion methods [ 17 , 18 ]. Moreover, hybrid materials will have the properties of their components simultaneously, either inorganic or organic [ 11 , 18 , 19 ]. In the last five years, incorporating ionic liquid cations (ILCs) into organic-inorganic hybrid perovskite materials has shown the potential to increase the photoluminescent properties [ 19 ].…”

Unveiling White Light Emission of a One-Dimensional Cu(I)-Based Organometallic Halide toward Single-Phase Light-Emitting Diode Applications

“…Luminescent organometallic halides are solution-processable optoelectronic materials without a high-temperature sintering process, and they have recently gained growing interests in the field of solar cells, detectors, and LEDs. − Especially, electronic and optical properties of organometallic halides can be modified via designing different crystal structures and modulating the chemical compositions. − Self-trapped excitons (STEs) generally exist in organometallic halides with a soft lattice and localized carriers, and thus, the broadband white emission can be realized here. , Besides, white emission can also be realized via the multiple emission centers covering blue, green, and red regions by selecting metal halides with appropriate geometries and an organic cation. , In this respect, the white emission is realized without rare earth dopants, and the issues including distinct degradation rates and reabsorption of mixed phosphors are also overcome.…”
