The enhancement of the optical properties of CdS/PMMA by adding fullerence C60

Abstract The C60/CdS//PMMA nanocomposites were synthesized via the casting method. Prepared samples were analyzed by XRD, SEM, TEM, and FTIR analysis. UV–visible spectroscopy was used to evaluate optical properties of CdS//PMMA& C60/CdS//PMMA nanocomposite. The E g decreased from 2.65 eV to 2 eV with the increment CdS content. The C 60 nanoparticles have a significant influence, The absorption of C60 CdS/PMMA nanocomposite is enhanced compared to CdS/PMMA Fullerene is an effective strategy for improving CdS photocatalytic performance. This enhancement is due to the electronic transition of π to π * for C 60 and n to π * between the n orbit of the CdS and C60. Degradation efficiency is 17% for CdS/PMMA, and 33% for C60/CdS/PMMA nanocomposite. Thus C 60 /CdS/PMMA can be used for optoelectronic devices, solar cell applications and photocatalytic activity.
