Abstract

A complex of Nd(III) with 3,3’-[(4-chlorphenyl)methylene]bis-(4-hydroxy-2H-1-benzopyran-2-one) (symbol L15) was immobilized in poly(methylmethacrylate) (PMMA) films and the properties of the composites obtained were studied. The films contained 1 wt. % of the complex and were deposited by spin- and dip- coating techniques. The IR spectroscopy data prove the presence of the complex in the films. The morphology of the pure films and those containing the complex was investigated by scanning electron microscopy, transmission electron microscopy and atomic force microscopy. In order to understand the photoluminescent properties of nanocomposite films with Nd(III), the emission spectra were recorded and discussed. The immobilization of the complex in films does not disturb its optical properties. The morphology and the luminescent properties of the immobilized complexes indicate that they may be used for active components in optical devices..
