| description | The invention discloses a cation coordination type perovskite with a stable structure and a preparation method and application thereof, the molecular formula is [(4AMTP) PbBr2] 2PbBr4, and a 4AMTP coordinated PbBr2 unit forms a cation layer. The photoluminescence behavior of the [(4AMTP) PbBr2] 2PbBr4 shows crystal size dependence, the relatively large crystal shows purple blue emission, two peak values exist at 414 nm and 431 nm, and the relatively small particle size (lt; 50 [mu] m) shows a single emission peak at 425 nm. Meanwhile, the compound shows blue light photoelectric response under the illumination of 405 nm, the [(4AMTP) PbBr2] 2PbBr4 is used for preparing a single crystal device, and the on/off ratio is 175. Therefore, the [(4AMTP) PbBr2] 2PbBr4 becomes a promising candidate material for light emitting and photoelectric device application.
