This study investigates the integration strategies of quantum dots (QDs) within glass and polymer matrices to engineer high-performance quantum dot color converters (QDCCs) at the industrial scale. By optimizing light-scattering and propagation mechanisms, significant improvements in light extraction efficiency can be achieved. These research findings are of great significance for the development of QD-based lighting and display systems.
Quantum dots (QDs), with their exceptional optical properties, have emerged as promising candidates to replace traditional phosphors in lighting and display technologies. This study delves into the integration strategies of QDs within glass and polymer matrices to engineer advanced quantum dot color converters (QDCCs) at the industrial scale for practical applications. To achieve enhancements in the photostability and thermal stability of QDCCs, we explore two distinct approaches: the dispersion of QDs in a hydrophilic glass matrix via a sol-gel process and the incorporation of QDs into a non-polar acrylate monomer to formulate QD/polymer nanocomposites. This research further investigates the optical behaviors of these composites, focusing on their light-scattering and propagation mechanisms, which are critical for optimizing light extraction efficiency in QDCCs. Additional optical film and light-scattering particles can improve color conversion efficiency by similar to 140%. These advancements present a significant step forward in the development of high-performance, energy-efficient, QD-based lighting and display systems.
