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

open access: yesAdvanced 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.

Advances in Thermoelectric Cu2ZnSnS4: From Structure, Synthesis to Performance

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Thermoelectric technology has the capacity to directly convert waste heat into electricity and vice versa. For a long time, Cu2ZnSnS4 (CZTS) has been extensively researched in the domains of solar cells and photocatalysis due to its exceptional photovoltaic properties, but its wide bandgap prevents it from being favored in thermoelectrics ...
