用3-(三乙氧基硅基)丙基异氰酸酯(TESPIC)对两个由噻唑衍生的有机配体进行修饰，得到分子前驱体(P1和P2)。然后，以它们为桥联分子，与稀土离子配位，与正硅酸乙酯(TEOS)形成无机Si-O网络，经共水解和共聚反应制得有机-无机杂化材料(LnM1和LnM2，Ln=Eu和Tb)，并对其组成、微观结构和光物理性质进行了研究。所有材料都是无定形的，没有发生相分离。这些材料的光致发光性能表明，这些杂化材料都能表现出镧系离子的特征发光。测定了Eu3+杂化材料的红/橙比、衰减时间和发射量子效率。此外，根据发射光谱和5D0态寿命，从理论上估算了与Eu3+离子配位的水分子数目。
Two organic ligands derived from thiazole were modified by 3-(triethoxysilyl)propyl isocyanate (TESPIC) to achieve the molecular precursors (P1 and P2). Then, the organic-inorganic hybrid materials (LnM1 and LnM2, Ln = Eu and Tb) were obtained by using these as bridging molecules to coordinate with lanthanide ions and form inorganic Si-O networks with tetraethoxysilane (TEOS) after cohydrolysis and copolycondensation processes, whose composition, microstructures, and photophysical properties were studied. All of the materials were amorphous and no phase separation occurred. The photoluminescence properties of these materials revealed that all these hybrids can show the characteristic luminescence of lanthanide ions. The ratios of red/orange, decay times, emission quantum efficiency of Eu 3+ hybrid materials were also determined. Furthermore, the number of water molecules coordinated to the Eu 3+ ion was theoretically estimated on the basis of emission spectra and the lifetime of the 5 D 0 state.
