Scientists have developed glow-in-the-dark succulents that recharge in sunlight, providing a novel, sustainable alternative to artificial lighting. Injected with light-emitting compounds, these plants emit bright colors comparable to small night lights and hold potential for applications in architecture and urban planning. The research, published in the journal Matter, reveals that micron-sized afterglow particles facilitate enhanced multicolor luminescence in Echeveria ‘Mebina’ succulents by efficiently dispersing within their unique microstructure. This breakthrough allows the plants to glow for up to two hours after exposure to light. While further studies are needed on the long-term safety of these materials, the innovative method shows promise for creating low-intensity lighting solutions for various environments.
