Due to intrinsic defects in blue-light-emitting perovskite materials, the charge carriers are prone being trapped by trap states. Therefore, preparation of efficient materials remains a significant challenge. Herein, CsPb(Cl/Br)3 nanocrystal (NCs)@SiO2 structures were fabricated through hydrolyzing (3-aminopropyl)-triethoxysilane (APTS). SiO2 can passivate surface states NCs, suppress nonradiative recombination pathways and effectively stabilize NCs. NCs@SiO2 exhibits higher photoluminescence (PL) intensity lifetime compared those pure The enhancement exciton binding energy (Eb) leads increased PL NCs @SiO2, as demonstrated temperature-dependent spectra. Subsequently, 0.3 mm film NCs@SiO2/poly(methyl methacrylate) (PMMA) was optimizing casting method. effective protection provided PMMA, NCs@SiO2/PMMA excellent thermal, water, air stability. Moreover, also good flexibility, maintaining unchanged under bending conditions. Importantly, lead be well encapsulated preventing from leaking into environment. This research demonstrates potential for applications friendly environmental field optoelectronics, including light-emitting diodes (LEDs) flexible displays.
