Abstract

A nanocomposite consisting of lead sulfide (PbS) nanoparticles (NPs) with average diameter of 26 ?, according to absorption threshold shift, and polyvinyl alcohol (PVA) was characterized using far-infrared absorption spectroscopy. The experimental results are consistent with theoretical calculations that include proper mechanical boundary conditions at the nanocrystal-host interface.

Highlights

  • The usage of nanoparticles (NPs) as polymer fillers relates to the strong current interest in development and application of new materials [1, 2]

  • A nanocomposite consisting of lead sulfide (PbS) nanoparticles (NPs) with average diameter of 26 Ǻ, according to absorption threshold shift, and polyvinyl alcohol (PVA) was characterized using far-infrared absorption spectroscopy

  • The far infrared spectra of PVA were recorded to ensure that any observed features were not due to the host material
