Li⁺-evaporation doped KSr₂Nb₅O₁₅ ceramic

Photochromic contrast nearly tripled

Indirect vacancy regulation via Li⁺ evaporation enhances effective color center concentration while controlling defect distribution, overcoming the intrinsic trade-off between trap content and depth, and significantly boosting photochromic performance without damaging the lattice electronic structure.
