摘要：

This study investigates the luminescence efficiency of red-emitting quantum-dots in supraparticles, a new type of microscopic photonic source. We demonstrate that compound supraparticles, created by incorporating higher-bandgap quantum dots in their design, reduce energy transfer losses and increase quantum dot luminescence efficiency.
