Descripción
Sumario:[Image: see text] In this study, inorganic perovskite (CsPbBr(3)) quantum dots are wrapped in SiO(2) to provide better performance against external erosion. Long-term storage (250 days) is demonstrated with very little changes in the illumination capability of these quantum dots. While in the continuous aging procedure, different package architectures can achieve very different lifetimes. As long as 6000 h of lifetime can be expected from these quantum dots, but the blue shift of emission wavelength still needs more investigation.
