In this study, inorganic perovskite (CsPbBr₃) quantum dots are wrapped in SiO₂ 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.

具有光学泵浦远程薄膜封装的二氧化硅封装钙钛矿量子点发光器件的长期可靠性得到改善。

在这项研究中，无机钙钛矿（CsPbBr ₃）量子点包裹在SiO _2中，以提供更好的抗外部侵蚀性能。这些量子点的照射能力几乎没有变化，证明可以长期保存（250天）。在连续老化过程中，不同的封装体系结构可以实现非常不同的使用寿命。从这些量子点可以预期到6000小时的寿命，但是发射波长的蓝移仍然需要更多的研究。
