“…The encapsulation of lead halide perovskite fluorescent materials with special substrates [such as SiO 2 , Al 2 O 3 , TiO 2 and metal-organic frameworks (MOFs)] can effectively improve their stability. For example, Jiang et al [25] synthesized CsPbBr 3 @SiO 2 fluorescent composites by incorporating tetraethyl orthosilicate into CsPbBr 3 perovskite nanocrystals prepared in advance by the thermal injection method. The fluorescent composites prepared by this method exhibit good UV stability and moisture resistance.…”

Organic-inorganic hybrid perovskite quantum dots have become a very widely used semiconductor light-emitting material. However, perovskite quantum dots face stability challenges, which are the key factors hindering their application. In this paper, by introducing water into the synthesis of FAPbBr3 pervoskite, ultra-stable FAPbBr3@PbBr(OH) fluorescent material was prepared. The photoluminescence intensity of the material after the addition of water increased 2.9 times compared with that before the addition of water. The excellent green fluorescence emission was still maintained after four times wash-dry experiments. Meanwhile, it also exhibits good ultraviolet and thermal stability. The above enhanced performance of FAPbBr3 quantum dots is attributed the protection of PbBr(OH). In addition, the prepared material can be used as anti-counterfeit patterns. The anti-counterfeit patterns have good color rendering, and the luminous color has a high dependence on temperature. Both of these features make it very valuable for various fluorescent anti-counterfeiting labels.

All‐inorganic cesium lead halide (CsPbX3, X = Cl, Br, I) perovskite nanocrystals have drawn great interest because of their excellent photophysical properties and potential applications. However, their poor stability in water greatly limited their use in applications that require stable structures. In this work, a facile approach to stabilize CsPbBr3 nanowires is developed by using SU‐8 as a protection medium; thereby creating stable CsPbBr3/SU‐8 microstructures. Through photolithography and layer‐by‐layer deposition, CsPbBr3/SU‐8 is used to fabricate bilayer achiral microswimmers (BAMs), which consist of a top CsPbBr3/SU‐8 layer and a bottom Fe3O4 magnetic layer. Compared to pure CsPbBr3 nanowires, the CsPbBr3/SU‐8 shows long‐term structural and fluorescence stability in water against ultrasonication treatment. Due to the magnetic layer, the motion of the microswimmers can be controlled precisely under a rotating magnetic field, allowing them to swim at low Reynolds number and tumble or roll on surfaces. Furthermore, CsPbBr3/SU‐8 can be used to fabricate various types of planar microstructures with high throughput, high consistency, and fluorescence properties. This work provides a method for the stabilization of CsPbBr3 and demonstrates the potential to mass fabricate planar microstructures with various shapes, which can be used in different applications such as microrobotics.
