Pristine samples of polyvinyl chloride (PVC) in addition to other samples containing different dopant levels of the synthesized cadmium selenide quantum dots (CdSe QD's) were successfully prepared using the traditional liquid casting route. X-ray diffraction (XRD), Fourier transform Infrared (FT-IR), and Ultraviolet/Visible (UV/Vis.) spectroscopic measurements were employed to retrace structural variations in the structure associated with increasing dopant levels of CdSe QD's. X-ray diffraction pattern of synthesized CdSe QD's reveals the hexagonal crystalline structure belongs to Wurtzite and in agreement with that of the Joint Committee on Powder Diffraction Standards (JCPDS). The amorphous nature of studied samples points out the interstitial position taken by the dopant CdSe Qd's. Fourier transform infrared shows repetitive spectral data indicating physical interaction between dopant and polymeric matrix and supporting XRD findings. UV/Vis. Electronic spectra reveal a quiet change in the optical energy gap resulting from the increasing level of dopant within the polymeric matrices
