Fluorescent nanohybrid materials, europium(III) complex ([EuCl2(Phen)2(H2O)2]ClㆍH2O) intercalated hectorite clay (laponite XLG), were obtained through ion exchange reaction of interlayer sodium cation with europium complex ion. The intercalated complex maintains a characteristic red 5D0-7F2 emission at wavelength 617 nm, which is comparable to the free complex. To increasing the processing ability such as adhesion, flexibility and hydrophobicity of fluorescent clay nanohybrid, the obtained particle is coated with polypropylene polymer (M.W. = 250,000). Structural and morphological characterizations were done using powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM). The component and thermal stability of the product were measured by Fourier transform infrared (FT-IR) spectroscopy, thermal analysis (TG-DTA), elemental analysis (CHN/ICP-AES). Optical and hydrophobicity of the obtained nano-composite were studied with UV-vis and fluorescence (PL) spectroscopies along with water contact angle measurement.
