Structural and Optical Characterization of ZnO-Graphene Nanocomposite Quantum Dots

In this research, zinc oxide quantum dots and graphene nanocomposites were synthesized via two different methods; In the first (direct) method, ZnO-graphene Nanocomposites were made mixing the synthesized zinc oxide and graphene. In the second (indirect) method, zinc nitrate, graphene, and sodium hydroxide were used to made ZnO-graphene Nanocomposites. XRD, FTIR and Raman spectroscopy analyses ...

Optical, Thermal and Structural Properties of CdS Quantum Dots Synthesized by A Simple Chemical Route

The present work deals with the synthesis and characterization of CdS nanoparticles with good thermal stability and optical properties by a novel and simple synthetic route. The nanoparticles were synthesized via chemical precipitation method in a single reaction vessel under ambient conditions. The prepared CdS nanoparticles were compared with the bulk CdS. The Optical properties were determin...
