Abstract By alloying GaN with AlN the emission of AlGaN light-emitting diodes can be tuned
to cover almost the entire ultraviolet spectral range (210–400 nm), making ultraviolet light …

Laser‐driven projection display puts forward urgent demand for color converter materials to
achieve wide‐color‐gamut and high‐quality image presentation. In this study, a hierarchical …

About twenty years ago, in the autumn of 1996, the first white light‐emitting diodes (LEDs)
were offered for sale. These then‐new devices ushered in a new era in lighting by …

Emerging technologies, such as smart wearable devices, augmented reality (AR)/virtual
reality (VR) displays, and naked-eye 3D projection, have gradually entered our lives …

Gallium nitride (GaN) light-emitting-diode (LED) technology has been the revolution in
modern lighting. In the last decade, a huge global market of efficient, long-lasting, and …

Solid‐state lighting is advancing toward higher power, higher brightness, and smaller size to
cope with the market competitiveness, and laser‐driven solid‐state lighting technology is …

Efficiency roll-off is a major issue for most types of light-emitting diodes (LEDs), and its
origins remain controversial. Here we present investigations of the efficiency roll-off in …

Ultraviolet (UV) detectors have attracted considerable attention in the past decade due to
their extensive applications in the civil and military fields. Wide bandgap semiconductor …

High‐radiance near‐infrared (NIR) phosphor‐converted light‐emitting diodes (pc‐LEDs) are
demanded for wearable biosensing devices and the properties of these pc‐LEDs are highly …
