Abstract
Colloidal quantum dots (QDs) applied in illuminants and displays have been offered great prospects due to their narrow and tunable emission bands. However, the QD's incompatibility to encapsulant and sensitivities to oxygen and moisture are still limiting their performance in white light emitting diode (WLED). In this research, we have developed a new kind of QDs composites as QDs luminescent microspheres (QLMS). QLMS is a new kind of highly robust QD composite featuring of high efficiency, narrow FWHM and excellent long-term operation stability. QLMS is fully compatible with current LED packaging process and can be used as phosphors for direct On-Chip applications. QLMS provide a promising way for QDs-optimized WLED with high efficiency, color rendering and stability.
