Investigate methods to enhance the stability of InP quantum dots by addressing photooxidation.
Developed a composite passivation approach using SiO2@TiO2 materials
Analyzed the effects of water and oxygen adsorption on quantum dot stability
Conducted experiments under photoexcitation to assess changes in stability
Significant reduction in photooxidation rates was observed with composite passivation
Enhanced stability leads to improved performance of quantum dots in lighting applications
Abstract
The stability of quantum dots (QDs) is primarily limited by photooxidation of their surface, and the adsorption of water and oxygen significantly affects this. Under photoexcitation, adsorbed H2O and O2...
