Structural and Optical Characterization of Curcumin Decorated on Exfoliated MoS2 Nanosheets by Chemical Method

Abstract

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.
