The invention discloses a six-core copper-sulfur nanocluster luminescent material and a preparation method thereof, and application of the material to fluorescent sensing detection of a tetracycline solution. The name of the luminescent material disclosed by the invention is Cu6DMMP6, and DMMP in the formula is 4, 6-dimethyl-2-mercaptopyrimidine as a sulfur-containing sulfydryl ligand; cuSO4 and a ligand are subjected to an in-situ reduction reaction and a coordination reaction in an aqueous solution to prepare the CuSO4 ligand. The material has high luminous intensity and can be used as a luminescent material; after the material is placed in a tetracycline methanol solution and a tetracycline aqueous solution, the fluorescence sensing response characteristic of fluorescence quenching is quickly presented, and the response has good selectivity; the material is easy to prepare, has good solubility and stability, and is suitable for detection in various solution environments.

The invention discloses a cuprous complex with fluorescence sensing performance on DMF (Dimethyl Formamide) and various pyridine VOCs (Volatile Organic Compounds), a fluorescence sensing device in a composite form of the cuprous complex and a preparation method of the cuprous complex. The cuprous complex luminescent material with good luminescent property and thermal stability is conveniently and cheaply prepared through a ball-milling coordination reaction of cuprous ions and ligands, and it is found that the cuprous complex luminescent material can selectively respond to DMF and various pyridine VOCs in various VOC atmospheres after being prepared into a film sensing device. Especially, when DMF and 3-phenylpyridine are converted from orange yellow light to blue light, ratio-type fluorescence sensing response is shown. The method for preparing the fluorescent sensing thin film device has the advantages that the process is simple and convenient, the prepared device is flexible and diversified ...
