SYNTHESIS, STRUCTURAL AND LUMINESCENCE PROPERTIES OF PEG/PVP BLEND POLYMER FILMS CONTAINING Er3+ DOPED CeO2

In this study well-blended Erbium:Cerium oxide doping polyethylene/ polyvinylpyrrolidone blended polymer films were synthesized using a simple solution casting synthesis approach. The changes in crystallization behavior, and luminescence and structural properties of polyethylene glycol and polyvinylpyrrolidone with the addition of cerium oxide and erbium ion have been investigated through FT-IR spectroscopy, X-ray diffraction and luminescence properties. The results show that adding the proper amount of CeO2:Er3+ nanoparticles can play the role of the further nano-filler, which is beneficial to improve the luminescence of blended oxide film. This study contributes to the understanding of the role of interfacial sites in metal and oxide support in blended films for the development of fertile luminescence materials.
