Efficient Visible Light Charging for Rare Earth‐Free Persistent Phosphor
Persistent phosphor, as an eco-friendly energy storage material, usually needs high-energy photonic rays in the storage process, such as ultraviolet (UV) light, X-ray, or even γ-ray. This strict requirement for light source which is harmful to human health greatly limits the popularity of persistent phosphors in the daily life.
