| description | The invention discloses a transition metal alloyed low-lead perovskite quantum dot and a preparation method and application thereof, and relates to the technical field of luminescent material preparation. According to the preparation method of the transition metal alloyed low-lead perovskite quantum dot provided by the invention, APTES (3-aminopropyltriethoxysilane) is used as an ion exchange accelerant, and basic transition metal halide B (OH) X is used as a transition metal donor, so that replacement of transition metal divalent cations and lead ions in lead-containing perovskite is completed; the lead content in the lead-containing perovskite is reduced to 50% or below, meanwhile, due to the fact that the structure is kept unchanged, the fluorescence quantum efficiency of the obtained perovskite still reaches up to 90.6% or above, the perovskite has excellent thermal stability, and the fluorescence intensity at the temperature of 100 DEG C still can be kept 60% or above of the normal-temperature fluorescen |
