Interaction between reduced graphene oxide (rGO) and PbSe quantum dots (Q-PbSe) have been studied by Cyclic Voltammetry (CV), Raman and FTIR spectroscopy. For that, the composites of Q-PbSe and rGO have been prepared by a one pot synthesis method. From the TEM analysis, Q-dots decorated on graphene layer have been concluded. Cyclic Voltammetry techniques have been employed to determine the change in quasi-particle gap and band edge parameters of Q-PbSe due to the interaction with rGO. The results were corroborated with FTIR and Raman analysis where substantial change in IR bands and shift in the Raman peaks have been observed, due to the interaction between Q-PbSe and rGO.
