Abstract The fluorescent and transparent multifunctional film was fabricated from photoluminescent Eu(Phen)2-laponite (Phen; 1,10-phenanthroline) and transparent poly(methyl methacrylate) (PMMA). Photoluminescent europium(III) complex ([EuCl2(Phen)2(H2O)2]Cl·H2O) intercalated hectorite clay (laponite XLG) nanohybrids were obtained through the ion exchange reaction of interlayer sodium cation with europium complex ion. Subsequently, Eu(Phen)2-laponite was suspended in tetrahydrofuran solution with dissolved PMMA by ultrasonic treatment, and then we obtained the multifunctional PMMA/Eu(Phen)2-laponite nanocomposite by drop-coating on glass. Structural and morphological characterizations were done using powder X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The component and thermal stability of the product were measured by Fourier transform infrared (FT-IR) spectroscopy and thermal analysis (TG-DTA). Transmittance and optical properties of the obtained nanocomposite were studied with UV-vis and fluorescence (PL) spectroscopies.
