Abstract The exploration of lead‐free halide perovskite nanocrystals (NCs) with intriguing optical properties is highly desirable owing to the toxicity and instability lead NCs. Here, a new kind uniform double Cs 2 NaBiCl 6 NCs are reported as versatile hosts accommodate ionic dopants for improving especially photoluminescence (PL). In contrast low deep‐blue PL quantum yield only 1.7% as‐synthesized pristine NCs, can be impressively regulated enhanced via doping Ag + , Mn 2+ or Eu 3+ ions in...

Lead halide perovskite nanocrystals (NCs) are promising optical materials in many fields. However, their poor moisture stability, significant toxicity, and difficulty to be further functionalized greatly hinder applications bioimaging. Here, a universal strategy is demonstrated by simply encapsulating CsPbX3 (X = Cl, Br, I) NCs into phospholipids achieve CsPbX3-phospholipid micelles (CsPbX3@phospholipid) as probes for multiplex encoding cellular imaging or tumor-targeted imaging. The layer...
