| titleOfInvention | Method for preparing near-infrared two-region fluorescent silver sulfide quantum dots in water phase |
| abstract | The invention discloses a method for preparing near-infrared two-zone fluorescent silver sulfide quantum dots in a water phase, which comprises the following steps: the method comprises the following steps: firstly, adding a cationic surfactant into water, heating until the cationic surfactant is completely dissolved, and then reducing the temperature of an aqueous solution of the cationic surfactant to 25-35 ℃; step two: slowly adding a sodium sulfide solution into the cationic surfactant aqueous solution obtained in the step one, uniformly stirring, and then adding a silver nitrate solution, and uniformly stirring; step three: and (4) heating the solution obtained in the step two to 35-100 ℃, and reacting to obtain the near-infrared two-zone fluorescent silver sulfide quantum dot aqueous solution. The invention has the advantages that: the preparation method is simple, the conditions are mild, the inert gas protection is not needed, the repeatability is good, the amplification is easy, and the prepared silver sulfide quantum dots have good water solubility, photobleaching resistance and high fluorescence intensity in a near-infrared two-region. |
