Conspectus With nearly 20% of global electricity consumed by lighting, more efficient
illumination sources can enable massive energy savings. However, effectively creating the …

Layered halide perovskites offer a versatile platform for manipulating light through synthetic
design. Although most layered perovskites absorb strongly in the ultraviolet (UV) or near-UV …

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 …

Through structural and optical studies of a series of two-dimensional hybrid perovskites, we
show that broadband emission upon near-ultraviolet excitation is common to (001) lead …

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 …

The effect of chemical-composition modification on the chiroptical property of chiral organic
ammonium cation-containing organic inorganic hybrid perovskite (chiral OIHP) is …

Inexpensive and highly efficient luminescent materials based on multinary halides have
received increased attention in recent years. Among those considered most promising are …

Two-dimensional (2D) hybrid lead halide perovskites are potential candidates for high light
yield scintillators as they have small band gaps between 3 and 4 eV and large exciton …

Lead halide perovskites are extensively investigated as efficient solution-processable
materials for photovoltaic applications. The greatest stability and performance of these …
