Unity Quantum Yield of High‐Entropy Quantum Dots Composited With Photonic Crystals for Information Encryption

Advanced Science, Volume 13, Issue 43, 3 August 2026.
This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

Bright and Durable Copper‐Iodide‐Based Nanowire Scintillators

Aggregate, Volume 7, Issue 8, August 2026.
A surface‐protective‐agent (SPA)‐coordinated low‐temperature crystallization strategy regulates the surface microenvironment of CsCu2I3 nanowires at the atomic level. The SPA simultaneously suppresses iodine‐vacancy‐related defects and nonradiative recombination while eliminating Cu2+ species and surface oxide formation, offering a coherent pathway to ...
