Organic-inorganic hybrid materials doped with Eu3+, Tb3+, La3+ and lithium ions

Organic-inorganic hybrid materials doped with Eu³⁺, Tb³⁺ La³⁺ and lithium ions were produced by sol-gel method using Tetraethyl orthosilicate and poly(methyl methacrylate), ethyl methacrylate, butyl methacrylate, ethyl acetyloacetate as inorganic and organic precursors. Morphology and structure of the hybrids heated at 125°C were characterized by Scanning electron microscopy equipped with Energy dispersive X-ray spectroscopy (SEM/EDS, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), 29Si MAS Nuclear Magnetic Resonance. In all the hybrids, photoluminescence emissions from (⁵D3), ⁵D4 →⁷FJ and ⁵D0→⁷FJ transitions of Eu³⁺ and Tb³⁺ ions, were revealed.
