技術摘要:
Halide perovskite quantum dots (PQDs) are promising materials for diverse applications including high phosphors, light-emitting diodes, and color filters due to their intriguing properties such as tunable bandgap, high photoluminescence quantum yield (PLQY) and narrow emission peaks. Despite the prosperous achievements over the past several years, PQDs face severe challenge in terms of stability under different circumstances. Currently, researchers have overcome part of the stability problem, making PQDs sustain in water, oxygen and high-polar environments for long-term use. However, halide PQDs can still be easily degraded under continuous excitation, which significantly limit their potential for conventional applications. In this study, we develop an oleic acid/oleylamine (traditional surface ligands)-free method to fabricate perovskite QD papers (PQDP) by adding cellulose nanocrystals (CNC) as long-chain interactive binding ligands that stabilize the PQD structure. As a result, the PLQY of as-fabricated PQDP remains over ~90% of its initial value under continuous ultraviolet (UV, 16 W) excitation for 2 months, showing almost no photo degradation behavior. This proposed method paves a way for the fabrication of ultra-stable PQDs and related applications.
