The invention relates to a cesium manganese halide perovskite analogue nanocrystal and aramid fiber composite luminescent material and a preparation method thereof. The method comprises the following steps: 1, preparing a precursor solution; 2, dissolving a halogen source; and 3, heating and stirring the obtained precursor solution and a halogen source to synthesize cesium-manganese halide perovskite analogue nanocrystals, and adjusting the reaction time to obtain products with different sizes and forms. According to the method, a low-temperature stirring reaction method is simple, easy to operate and low in cost, and the obtained nanocrystal analogue is good in form, relatively uniform in diameter distribution and relatively good in fluorescence property and stability; and compounding the prepared cesium manganese halide perovskite analogue nanocrystals with aramid fiber/polyphenylene sulfide fiber composite paper (ACFs/PPS) to obtain the luminescent material. The preparation method is simple in process and
