Organic light‐emitting diodes (OLEDs) have come a long way ever since their first
introduction in 1987 at Eastman Kodak. Today, OLEDs are especially valued in the display …

Organic semiconductors are solution-processable, lightweight and flexible and are
increasingly being used as the active layer in a wide range of new technologies. The …

Perovskite light-emitting diodes (LEDs) have attracted broad attention due to their rapidly
increasing external quantum efficiencies (EQEs),,,,,,,,,,,,,–. However, most high EQEs of …

Abstract Light-emitting diodes (LEDs), which convert electricity to light, are widely used in
modern society—for example, in lighting, flat-panel displays, medical devices and many …

A major efficiency limit for solution-processed perovskite optoelectronic devices, for example
light-emitting diodes, is trap-mediated non-radiative losses. Defect passivation using organic …

Efficient organic emitters in the deep‐red region are rare due to the “energy gap law”.
Herein, multiple boron (B)‐and nitrogen (N)‐atoms embedded polycyclic heteroaromatics …

Near‐infrared (NIR) luminescence materials with broadband emissions are necessary for
the development of light‐emitting diodes (LEDs) based light sources. However, most known …

A spin-flip from a triplet to a singlet excited state, that is, reverse intersystem crossing (RISC),
is an attractive route for improving light emission in organic light-emitting diodes, as shown …

Luminescent metal halide materials with flexible crystallography/electronic structures and
tunable emission have demonstrated broad application prospects in the visible light region …

Ultra‐efficient broadband near‐infrared (NIR) phosphor‐converted light‐emitting diodes (pc‐
LEDs) are urgently needed to improve the detection sensitivity and spatial resolution of …
