Abstract:
Participation of a polymericmedia in light-emitting processes of composite nano-CdS/polyvinyl alcohol is studied by
probing different absorption-emission routes via adjustment of excitation wavelengths. It is shown that the polymeric
constituent of the composite contributes chiefly to the photoluminescence excitation processes via absorption
and excitation transfer to the embedded CdS nanoparticles while the composite emission occurs mostly
within the nanoparticles.
