Zero-dimensional (0D) all-inorganic/organic–inorganic metal halides, as emerging
luminescent materials, have attracted unparalleled interest from versatile perspectives due …

Abstract Replacing methylammonium (MA+), formamidine (FA+), and/or cesium (Cs+) in 3D
metal halide perovskites by larger organic cations have built a series of low‐dimensional …

The high‐profile candidacy of low‐dimensional metal‐halide single crystals as promising
light emitters originates from the intriguing emission properties (eg, extremely broad …

Energy‐saving white lighting from the efficient intrinsic emission of semiconductors is
considered as a next‐generation lighting source. Currently, white‐light emission can be …

Metal halide perovskites (MHPs) are in a blossoming status where their inherent
optoelectronic properties are being revisited from the perspective of both fundamental …

2D metal halide perovskites can show narrow and broad emission bands (BEs), and the
latter's origin is hotly debated. A widespread opinion assigns BEs to the recombination of …

Organic-inorganic metal halide hybrids are an important class of crystalline materials with
exceptional structural and property tunability. Recently metal halide perovskites with ABX 3 …

Excitation‐dependent emission (Ex‐de) materials have been of considerable academic
interest and have potential applications in real life. Such multicolour luminescence is a …

Low-dimensional hybrid metal halides demonstrate broad-band emission and high
photoluminescence quantum yield (PLQY) acting as excellent candidates for a new …

Broadband emission is attributed to the formation of self-trapped excitons (STEs) due to the
strong electron–phonon coupling. Interestingly, it has been observed in only certain three …
