Kurzfassung:
A novel sensor based on Ag 2 S/chitosan films was prepared via a coordination-driven self-assembled method. Experiments demonstrated that Ag 2 S was inert to chitosan film. Structural, and sensing property studies were realized by FTIR, DSC, SEM, and fluorescence analysis.
DSC showed good crystallization after manipulation, showing that the Ag 2 S QDs were uniformly distributed in the film, leading to a good fluorescence property. The fluorescence of the films was selective to benzaldehyde. The linear detection on benzaldehyde concentration by the fluorescence
method can be established was from 0 to 10 8 mg/L. The films could be quenched because of the electron transfer between benzaldehyde and Ag 2 S QDs. It would therefore be developed as an optical sensor.
