Organic–inorganic halide perovskites have attracted extensive attention due to their
excellent optoelectronic properties. However, the toxicity of heavy atom Pb2+ and instability …

Over the past few decades, the design and development of carbon materials have occurred
at a rapid pace. In particular, these porous graphene‐like carbon nitride materials have …

The Tauc plot is widely used to determine the bandgap of semiconductors, but the actual
plot often exhibits significant baseline absorption below the expected bandgap, leading to …

The introduction of a two-dimensional (2D) perovskite into a three-dimensional (3D)
perovskite has been proven to be effective in minimizing defect state density and improving …

Maximizing the regeneration of singlet excitons remains a considerable challenge in deep-
blue emission systems to obtain low-cost, high-efficiency fluorescent materials. However, the …

The excellent luminescence properties and structural dynamics driven by the stereoactivity
of the lone pair in a variety of low‐dimensional ns2 metal halides have attracted growing …

The instability of the metal halide perovskites upon exposure to moisture or heat strongly
hampers their applications in optoelectronic devices. Here, we report the large-yield …

The interaction of light with solids can be dramatically enhanced owing to electron‐photon
momentum matching. This mechanism manifests when light scattering from nanometer …

Oxygen vacancies on the surface of the electron transport layer (ETL) can distort the
perovskite structure near the interface, inducing unfavorable phases, and, the surface …

Perovskite light‐emitting diodes (PeLEDs) have attracted both academic and industrial
interest because of their high efficiency, wide color gamut as well as low material and …
