Chemists developed a way to significantly improve the performance of light-emitting diodes (LEDs) made with perovskite. The ...

Blue light is vital for light-emitting devices, lighting applications, as well as smartphone screens and large screen displays. However, it is challenging to develop efficient blue organic ...

Organic light-emitting diodes are used in smart phones, tablets, and large TV screens. As they do not need any additional background illumination, they are energy-efficient. The can be produced at low ...

Emory University chemists discovered a hidden solution-phase reaction pathway that boosts the quantum efficiency of ...

Key challenges in the development of InP-based QDs and ZnSe-based QDs. Colloidal quantum dots (QDs) exhibit exceptional properties of narrow-band emission, tunable luminescent wavelength, high ...

Researchers report deep-red mixed-halide perovskite LEDs reaching 21.70 percent external quantum efficiency and a 26.39-hour ...

At-home LED devices, particularly those that combine red and blue light, are efficacious for acne and can likely complement other over-the-counter and prescription treatments. HealthDay News — At-home ...

An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...
