Graphene-based white LEDs could be "green" and efficient

Researchers from Taiwan have demonstrated a white LED consisting of a strontium-based metalorganic framework (MOF), graphene, and inorganic semiconductors, which can generate a bright white light emission.

White LEDs can be long-lasting and energy efficient, but white LEDs are currently made with rare-earth elements, and mining these minerals can be costly and produce toxic waste. Additionally, existing commercial methods for producing white LEDs involve multiple components and steps that hamper efficiency and quality.
