The invention belongs to the technical field of laser, and relates to a nanometer composite material FAPbBr3/SiO2 and a preparation method thereof, and applications in two-photon pumping nanometer random laser devices. The preparation method comprises: taking absolute alcohol, deionized water, ammonia water and tetraethyl orthosilicate (TEOS), mixing and stirring, purifying, and drying to obtain SiO2 nanospheres; injecting absolute alcohol and 3-aminopropyltriethoxysilane (APTES) into the SiO2 nanospheres, purifying, and drying to obtain aminated SiO2 nanospheres; dissolving FABr and PbBr2 into DMF, fully stirring, and pouring the aminated SiO2 nanospheres into the prepared solution to prepare a quantum dot solution A; adding oleic acid and oleylamine into the quantum dot solution A, and stirring to obtain a solution B; taking a small amount of the solution B, and adding into a trichloromethane solution in a dropwise manner; and carrying out centrifugal purification on the precipitatedproduct to obtain the nanometer composite material FAPbBr3/SiO2.
