Detection of fungicide in water by ZnCdSe quantum dots thin film

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Quantum dots (QDs) thin film sensor was developed to detect fungicide in water by optical sensing system. The ZnCdSe QDs was synthesized using a wet-chemical process to apply in this fluorescent sensor. A sensor system was setup, comprises an excitation light source made of laser diode, a dual arm fiber optic probe, a spectrometer and sensor chamber. The QDs thin film was deposited by dropping QDs solution onto the probe surface and let them dried in the ambient temperature. The detection of fungicide was done by comparing the photoluminescence (PL) spectra of the thin film dipped in the deionised water and in fungicide solutions. The PL spectrum of the thin film was quenched by the presence fungicide solutions where the drop of PL peak intensity is depended on the concentration of fungicide solutions.
