Abstract
ZnO nanoparticles embedded in polyvinylpyrrolidone matrix were fabricated in situ by colloidal
method with environmentally friendly reaction conditions. The colloid was used to form solid
nanocomposite polyvinylpyrrolidone/ZnO, and optical properties of the material were studied. Two types of
emission were identified in the nanocomposite: one originates from the polymeriс matrix another is related
the defect states in ZnO nanoparticles. Specific way of light emission excitation via energy transfer from
the polymeric matrix to nanoparticles was observed.
