Structural and Optical Characterization of Curcumin Decorated on Exfoliated MoS 2 Nanosheets by Chemical Method

In this study, we developed a simple and effective chemical method for preparing curcumin nanoparticles decorated on exfoliated MoS₂ nanosheets using solution blending method. Its structural and optical properties were studied. The structural results show that a uniform and homogeneous distribution of curcumin nanoparticles on MoS₂ nanosheets. From the absorption studies reveals that curcumin loaded on exfoliated MoS₂ nanosheets exhibits significantly higher absorption than bare exfoliated MoS₂ nanosheets. The photoluminescence spectroscopy results show that these samples have enhanced fluorescence and lifetime of this material is found to be 12.3ns. Because of its biocompatibility and fluorescence properties, it is a very promising material for biological applications such as bio imaging, drug delivery and so on.
