Insights into structural defect formation in individual InP/ZnSe/ZnS quantum dots under UV oxidation

Nature Communications
InP/ZnSe/ZnS quantum dots (QDs) stand as promising candidates for advancing QD-organic light-emitting diodes (QLED), but low emission efficiency due to their susceptibility to oxidation impedes applications. Structural defects play important roles in the
