In article number 2001626, Haiqin Sun, Qiwei Zhang and co‐workers propose an effective strategy to significantly improve luminescent switching contrast by more than 300% between luminescent and photochromic units by site‐selective occupancy engineering on BaMgSiO 4 :Eu 2+ photochromic materials. The fabricated flexible films exhibit excellent waterproof, flexibility, and stretchability characteristics, accompanied by reversible color switching and larger color contrast. They are particularly suitable for complex application environments in optical storage and rewritable flexible devices.
