- Abstract
In this paper, the synthesis of Fe3O4/CdTe nanocomposite has been reported and their sensing response to H2O2 is also discussed. Firstly, ethylenediaminetetraacetic acid capped Fe3O4 nanoparticles were synthesized followed by chemical conjugation with triethanolamine capped CdTe nanoparticles. The obtained Fe3O4/CdTe nanocomposite were characterized with X-ray diffraction, Fourier transformed infrared spectroscopy, scanning electron microscopy, UV-Vis spectroscopy and fluorescence spectroscopy. The Fe3O4/CdTe nanocomposites were found with excellent fluorescence and magnetic properties favorable for detection of H2O2. The fluorescence emission intensity decreased with increase in concentration of H2O2. The Fe3O4/CdTe nanocomposite showed fluorescence enhancement compared to CdTe nanoparticles.
