The present invention provides dimension-reducing perovskite and a preparation method and application thereof. The dimension-reduced perovskite is obtained by the transformation of another dimension-reduced perovskite, which solves the problem that the current dimension-reduced perovskite needs to be prepared by crystal growth in a pre-designed system, and the preparation method is limited. The preparation method of the dimension-reducing perovskite of the invention has the advantages of simple synthesis method, mild synthesis conditions, high crystal purity, strong controllability and high crystal conversion rate. Different dimensionality-reduced perovskite crystals can be generated by simply changing the reaction auxiliaries. The transformation of dimensionality-reduced perovskite crystals is formed at one time, saving time and effort. It has strong universality and practicability for the same type of crystal, which is conducive to popularization and use, and is suitable for solar cells, light-emitting diodes and other fields. |
