Frontispiece: Near‐Unity Photoluminescence Quantum Efficiency for All CsPbX3 (X=Cl, Br, and I) Perovskite Nanocrystals: A Generic Synthesis Approach

Perovskite Nanocrystals CsPbX3 (X=Cl, Br, and I) nanocrystals have been prepared that give near unity red, green, and blue photoluminescence quantum yields, as demonstrated by S. Baitalik, N. Pradhan, and co-workers in their Communication on page 5552 ff.
