In this study, inorganic perovskite (CsPbBr) quantum dots are wrapped in SiO 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.
在本研究中，无机钙钛矿（CsPbBr）量子点被包裹在SiO中，以提供更好的抗外部侵蚀性能。这些量子点的发光能力在长达250天的长期储存中变化极小。而在连续老化过程中，不同的封装结构会有截然不同的寿命。这些量子点有望达到长达6000小时的寿命，但发射波长的蓝移仍需更多研究。
