Custom Core-shell Hybrid Perovskite Quantum Dots
Inquiry
Core-shell perovskite quantum dots refer to organic-inorganic and hybrid perovskite quantum dots as the core, and a shell with a large band gap is grown around it, which is also called surface coating or encapsulation strategy. This method is considered to be an effective method to improve the stability of perovskite (also often used to improve the stability of other semiconductor quantum dots), especially the enhancement of the water stability of perovskite quantum dots. It can not only enhance the stability of the perovskite, but also does not affect the performance of the perovskite itself.
Background
Despite the organic-inorganic hybrid perovskite quantum dots (QDs) showed excellent photoelectric properties, but its inherent properties making it vulnerable to the influence of various external factors, such as surface defects are vulnerable to light, electricity, heat, oxygen and other attack prone to lead to structure damage and decomposition, and organic cation MA + and FA + etc. Also easy to degradation under the above factors.
In addition, there are some internal or internal factors, such as low formation energy, ion migration, electromigration and interface reaction, which will affect the stability of perovskite. All of the above factors will lead to significant attenuation of photoluminescence (PL) intensity and even quenching of fluorescence, which seriously hinder its commercial application. According to the research, the core-shell structure is an effective method to enhance the water stability and other stability of QDs.
