Tutorial Paper


Graphene semiconductor quantum dots (G-QDs) nanocomposites have attracted a lot of scientific interest. They have promising properties which allow them to be a good choice for photoelectric devices. G-QDs nanocomposites are prepared chemically by thermal decomposition of organometallic complex. Synthesis procedures were performed in the absence and presence of graphene in order to study its influence on the optical properties of the quantum dots (QDs) precisely. Various experimental techniques were utilized to study the morphology, crystal structure and the optical properties of the as-prepared materials using X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy and UV/visible spectrophotometer. This paper will discuss the coupling between graphene and QDs showing the quenching of QDs emission, slowing rate of particle growth, increasing stock shift and enhancing the particle size distribution.
