摘要

以正硅酸四乙酯和聚甲基丙烯酸甲酯、甲基丙烯酸乙酯、甲基丙烯酸丁酯、乙酰乙酸乙酯为无机前驱体，采用溶胶-凝胶法制备了掺杂Eu3+、Tb3+ La3+和锂离子的有机-无机杂化材料。采用扫描电子显微镜、x射线能谱(SEM/EDS)、x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、核磁共振(29Si MAS)等手段对125℃加热后的杂化产物的形貌和结构进行了表征。在所有杂化体中，发现了Eu3+和Tb3+离子的(5D3)、5D4→7FJ和5D0→7FJ跃迁产生的光致发光。

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.
