Embodiment 1
[0035] 26mLDMF, 2mL cyclohexanol and 2mL distilled water were mixed as solvent; 33.8mg europium nitrate (Eu(NO 3 ) 3 ), 21mgH 3 BTC and 2.4mg of carbon-based quantum dots co-doped with nitrogen and sulfur elements (N,S-CDs) were dissolved in the obtained solvent; 3 Adjust the solution to a pH value of 5; stir the prepared mixed solution at room temperature for 2 hours, put the mixed solution in an oven, heat it to 85°C under normal pressure and keep it reacting for 16 hours; After washing with DMF and ethanol and centrifuging three times, Eu-MOFs / N,S-CDs two-color fluorescent material was obtained by vacuum drying at 80°C for 5 hours, which is based on the fluorescence colorimetry of rare earth metal organic framework complex-carbon-based quantum dot organic solvent water content sensor.
Embodiment 2
[0037] 18mL of DMF, 6mL of cyclohexanol and 6mL of distilled water were mixed as solvent; 2.6mg of europium chloride (EuCl 3 ), 2.1mgH 3 BTC and 0.3mg of carbon-based quantum dots co-doped with nitrogen and sulfur elements (N,S-CDs) were dissolved in the obtained solvent; 3 Adjust the solution to a pH value of 4; stir the prepared mixed solution at room temperature for 0.5 hours, then place the mixed solution in an oven, heat it to 60°C under normal pressure, and keep the reaction for 48 hours; centrifuge after the reaction, and the obtained precipitate Washed with DMF and ethanol in sequence, centrifuged three times, and vacuum-dried at 50°C for 5 hours to prepare Eu-MOFs / N,S-CDs two-color fluorescent material, which is based on rare earth metal organic framework complex-carbon-based quantum dot organic solvent water content fluorescence Colorimetric sensor.
Embodiment 3
[0039] 27mLDMF, 2.7mL cyclohexanol and 0.3mL distilled water were mixed as solvent; 446mg europium nitrate hexahydrate (Eu(NO 3 ) 3 ·6H 2 O), 210mgH 3 BTC and 24mg of carbon-based quantum dots (N,S-CDs) co-doped with nitrogen and sulfur elements were dissolved in the obtained solvent; 3 Adjust the pH value of the solution to 6; stir the prepared mixed solution at room temperature for 5 hours, then transfer the mixed solution to a hydrothermal reaction kettle with a polytetrafluoroethylene liner and heat it to 100°C, and keep the reaction for 2 hours; after the reaction is completed After centrifugation, the resulting precipitate was washed with DMF and ethanol in sequence, and after centrifugation three times, it was vacuum-dried at 100°C for 2 hours to obtain Eu-MOFs / N,S-CDs two-color fluorescent material, which is based on rare earth metal organic framework complex-carbon-based quantum dot organic Fluorescent colorimetric sensor for solvent water content.
