| titleOfInvention | Manganese-doped CsPbBr3Perovskite quantum dot and molecular sieve composite luminescent material and preparation method and application thereof |
| abstract | The invention discloses manganese-doped CsPbBr 3 A perovskite quantum dot and molecular sieve composite luminescent material, a preparation method and application thereof belong to the technical field of luminescent materials. The method comprises the following steps: (1) stirring the molecular sieve and cesium bromide solution, centrifuging, washing and drying to obtain Cs + An exchanged molecular sieve; (2) preparing lead bromide and manganese bromide into bromide solution by using octadecene, oleic acid and oleylamine; (3) under the condition of inert gas and stirring, in octadecene, bromide solution and Cs + The exchanged molecular sieve is reacted, cooled, washed and dried to obtain the manganese doped CsPbBr 3 The perovskite quantum dot and the molecular sieve are compounded to form the luminescent material. The composite luminescent material has multimodal emission of blue light and green light regions, and the luminescent peak position and the intensity of each luminescent peak can be modulated according to the proportion of manganese ions and lead ions; the composite luminescent material has better environmental stability and can be used in the field of white light LEDs. |
