AQUEOUS SYNTHESIS OF NANOPARTICLES OF CADMIUM SULPHIDE

摘要

The invention relates to a method for the synthesis of fluorescent, semiconductive nanoparticles (NPs) of cadmium sulphide (CdS), comprising: a) mixing i. a thiol as a source of sulphur and as a covering compound; ii. a cadmium sa iii. a compound containing or generating a source of phosphate; b) adding a buffer solution to the mixture obtained in step (a), at a pH of between 7 and 10, in the presence or absence of oxygen and at a temperature of between 15 and 80°C; c) incubating the solution produced in b) at a temperature of between 15 and 80°C, for an incubation period of between 1 and 9 days, until fluorescence is obtained; and d) evaluating the fluorescence of the NPs of CdS, exposing them to a UV transilluminator (at 365 nm).
