Article Description

The development of multi-luminescent center-integrated phosphors with high-quality and tunable white light emission is highly desirable for practical applications in solid-state lighting, but it remains challenging. Herein, a novel strategy of integrating dyes and perovskite nanocrystals into different locations of metal-organic frameworks (MOFs) to achieve high-performance white lighting-emitting diodes (WLEDs) is proposed. Based on the emerging dye-encapsulated MOF system, CsPbX nanocrystals (NCs) with a high PLQY and tunable bandgap were utilized as additional emission centers, contributing to spectral complementarity and energy transfer. The spatial separation of dyes and CsPbX NCs results in no mutual interference between each other during loading, enabling more flexible emission tuning. The resulting LED based on the combination of ZIF-8⊃pm567A/SRh101@CsPbClBr-SiO and a 460 nm blue LED chip exhibits exceptional Commission Internationale de l’Eclairage (CIE) coordinates of (0.329, 0.334), a moderate correlated color temperature (CCT) of 5681 K and a high color-rendering index (CRI) of 88. In addition, cold and warm WLEDs were also realized by only fine-tuning the loading amounts of CsPbClBr NCs, without sacrificing the high CRI. This strategy offers a new perspective for the design of white light-emitting phosphors with excellent color quality and facilitates the advancement of high-performance WLEDs.
