Toward eco‐friendly and stable halide perovskite‐inspired materials for light‐emitting devices applications by dimension classification: Recent advances and opportunities

“…0D structure is obtained by further slicing 1D crystal structure, forming isolated polyhedron or polyhedronbased clusters. 85 Most recently, abundant compounds of 0D structure have been explored and investigated, such as Sn-, 108,109 In-, 110 and Cu-based metal halides, 57 in which metal-centered polyhedrons are separated by small inorganic cations (e.g., Cs + , Rb + ) or organic molecules with different lengths. 85 It should be mentioned that the 0D lead-free candidates can be called perovskite derivatives, because the structures of such materials do not have clear relations to the conventional perovskites.…”

“…Copyright 2020 the Royal Society of Chemistry X 3 metal halides, which is related to the differences of crystal structure and electronic band structure. 57 For Cs 3 Cu 2 X 5 , it has a much flatter valence band than that of CsCu 2 X 3 , which generates stronger exciton confinement effect and heavier electron and hole effective masses, leading to high efficiency emission. 102 More importantly, the 0D Cs 3 Cu 2 I 5 metal halides exhibit an excellent stability.…”

“…The direct bandgap characteristic, good carrier transport ability along the 1D chain‐like direction, together with the eco‐friendly feature, endow the emerging 1D copper halides with great application prospects in the optoelectronics field 57 . For instance, by using the 1D CsCu 2 I 3 SCs as the active medium, Fangʼs group realized a broadband photodetector with fast and facet‐dependent photoresponse, in which photogenerated electrons confined in edge‐shared tetrahedra double chains could quickly transport along the 1D transmission channel 104 .…”

“…Metal halides are of potential interest due to their application in semiconducting electronic devices, nanotechnology, optoelectronics, radiation detectors, etc. [1][2][3].…”

Gel Permeation Chromatography Process For Highly Oriented Cs3Cu2I5 Nanocrystal Film

“…More recently, the use of copper(I)-based lead-free perovskites as green materials has been demonstrated in the eld of optoelectronics [15][16][17][18][19][20][21][22][23][24][25][26][27][28] . The photoluminescence (PL) spectra of lead-free Cs 3 Cu 2 I 5 perovskite exhibited a deep blue emission with a broad full width at half maximum (FWHM) and a large Stokes shift, which is attributed to the strong self-trapped emission effect 29 .…”
