Anion exchange is a convenient postsynthetic transformation method to adjust the composition and bandgap of semiconductors. However, it is still a challenge to achieve the desired halogen-variable perovskites due to rapid and uncontrollable reaction and difficulty to synthesize directly. Herein, a f...
