Abstract:
The nanocomposite film was synthesized by dispersing the silica fluorescent ratiometric nanosensors in PVA film，and the prepared film was successfully applied in fluorescent sensing chloride ions on the surface of bronze wares. Transmission electron microscopy, scanning electron microscope, fluorescence spectrum method and digital fluorescence images experimental, were used to investigate the properties of chloride nanosensors, interaction between the nanocomposites film and bronze wares. Furthermore, a non-destructive method for fluorescent sensing chloride ions on the surface of bronze wares was investigated. Based on these findings, the fluorescent nanocomposite film was successfully used to detect chlorine ions on the surface of copper coins.
KeyWords:
fluorescent nanocomposites film; PVA; nanosensors; bronze wares
