In Situ Crystallization
In article number 2107452, Song Chen, Yu Chen, and co‐workers report a strategy for in‐situ crystallization of CsPbBr3 nanocrystals within silica nanospheres by a carefully designed, multistep, high‐temperature treatment. The image presents the well‐protected CsPbBr3 nanocrystals with excellent thermal stability, referencing the Chinese traditional story of “Bagua furnace alchemy...
Although all‐inorganic perovskite materials present multiple fascinating optical properties, their poor stability undermines their potential application in the field of multi‐color display. Herein, spatially confined CsPbBr3 nanocrystals are in situ crystallized within uniform mesoporous SiO2 nanospheres (MSNs) to regulate their size distribution, passivate their surface defects, shield them from...
