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 …

2D hybrid lead halide perovskites exhibit versatile photoluminescent behaviors for
narrowband to broadband emissions (BBEs) and have become attractive candidates for …

An expansive library of structurally complex two-dimensional (2D) and three-dimensional
(3D) lead halide perovskites has emerged over the past decade, finding applications in …

Low-dimensional organic–inorganic hybrid lead halides have opened up a new frontier in
single-component phosphors for white emission, which stems from self-trapped excitons …

Recently, cuprous halide perovskite-type materials have drawn tremendous attention for
their intriguing optical properties. Here, a zero-dimensional (0D) Cu (I)-based compound of …

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 …
