Ultra-bright deep-blue LEDs shine with eco-friendly copper-iodide hybrid material

A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an energy-efficient device at the heart of all major lighting systems.

Dual interfacial H-bonding-enhanced deep-blue hybrid copper–iodide LEDs

Solution-processed light-emitting diodes based on non-toxic copper–iodide hybrids1 are a compelling solution for efficient and stable deep-blue lighting, owing to their tunability, high photoluminescence efficiency and environmental sustainability2. Here we present a hybrid copper–iodide that shows near-unity photoluminescence quantum yield (99.6%) with an emission wavelength of 449 nm and colour coordinates (0.147, 0.087), alongside its emissio…

Deep-Blue LEDs Boosted by Dual H-Bonding

In the relentless pursuit of energy-efficient and environmentally benign light-emitting technologies, researchers have turned their attention toward novel hybrid materials that can revolutionize solid-state lighting. In a compelling advance, a team of scientists has unveiled a non-toxic copper–iodide-based hybrid that exhibits near-perfect photoluminescence quantum yield paired with stable, deep-blue emission. This breakthrough not only promises…

New Source of Brilliant Deep Blue Light

Despite the apparent brilliance of display screens that light up the world, deep blue hues are hard to come by. Now a team of scientists led by Rutgers University that includes researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has developed an approach for manufacturing light-emitting diodes (LEDs) that emit deep blue light with a wavelength of about 450 nanometers.
