description The invention relates to the technical field of perovskite optical devices, in particular to a blue-light CsPbBr3 perovskite thin film and a preparation method thereof. Comprising the following steps: preparing a Cs-DBSA precursor solution: mixing a cesium source, dodecylbenzene sulfonic acid and octadecene, and reacting in inert gas to prepare the Cs-DBSA precursor solution; a CsPbBr3 blue light perovskite precursor solution is prepared, specifically, the Cs-DBSA precursor solution and lead bromide are added into dimethyl sulfoxide, stirring is conducted, and the CsPbBr3 blue light perovskite precursor solution is prepared; and preparing a blue light CsPbBr3 perovskite thin film: spin-coating the transparent conductive substrate with the CsPbBr3 blue light perovskite precursor solution, and performing in-situ growth to prepare the blue light CsPbBr3 perovskite thin film. The blue light CsPbBr3 perovskite thin film has the advantages that the prepared blue light CsPbBr3 perovskite thin film simultaneously rea
