[0059] According to one aspect of the present invention, the present invention relates to a method for preparing a two-dimensional fluorescent MOFs composite material, comprising the following steps:
[0060] stirring the mixture of carbon quantum dots, 2-methylimidazole, soluble zinc salt and water to obtain a first mixed system; washing the emulsion in the first mixed system, and then dispersing the washed emulsion in water and dry.
[0061] Carbon quantum dots (CDs), as a novel nanoluminescent material with quantum size, have attracted much attention due to their excellent optical properties, low toxicity and high biocompatibility. CDs are good electron donors and acceptors due to their abundant surface sites and functional groups, easy structure modification, and excellent electron transfer properties. However, fluorescence quenching occurs due to the easy aggregation of CDs during electron transfer. Therefore, it is an effective way to solve the above problems by introd...

[0097] A method for preparing a two-dimensional fluorescent MOFs composite material, comprising the following steps:
[0098] Dissolve 0.5mL, 3mg / mL of CDs and 0.168g of 2-methylimidazole in 5mL of deionized water for 10min, then add 0.152g of Zn(NO 3 ) 2 ·6H 2 O. Magnetic stirring was used at 37°C for 2 h, and the resulting white emulsion was washed twice with deionized water; finally, the product was dispersed in 10 mL of deionized water and dried under vacuum at 60°C for 6 hours.
