Sunlight-Recharged Glow-in-the-dark Succulents New Way to Plant-based Lighting Systems

In a new study published in the journal Matter, researchers in China have developed a novel way to create glow-in-the-dark plants. Unlike previous methods that relied on genetic engineering, the research team injected succulents with special phosphor particles similar to those used in glow-in-the-dark toys. These materials absorb and store light, then re-emit it as a soft, continuous glow for up to two hours.

The team, led by materials scientist Xuejie Zhang from the South China Agricultural University in Guangzhou, found that succulents with their fleshy, dense leaves were ideal for this process, resulting in a strong and uniform glow. They used the succulent Echevaria 'Mebina', a common houseplant that grows rosettes of dense and fleshy leaves. The technology is also versatile, allowing for a wide range of colors, including blue-green, red, and white.

While the current method requires injecting each leaf, the researchers hope to use smaller particles in the future to simplify the process. They have applied for a patent and envision the technology being used for decorative lighting installations. While questions remain about the long-term health effects on the plants and the potential toxicity if ingested, the researchers see this as a promising and innovative way to bring light into living spaces.
