【摘要】 温度在科技领域中是非常重要的参数之一,光学传感器与其他类型传感器相比有很多的优点,比如灵敏度高、非接触式的操作等等。含稀土有机配合物的材料可以作为光纤维传感器的温度探针和热敏感探测器。近来有报道将稀土Eu³⁺和Tb³⁺化合物制成温度光纤传感器,有意思的是到目前为止,绝大多数基于稀土配合物的光学传感器主要集中在Eu³⁺化合物,而Tb³⁺化合物的报道非常少,这可能是由于Tb³⁺化合物的发光很少能展现出较高的温度敏感性,但另一方面,Tb³⁺化合物一般比Eu³⁺化合物具有较长的荧光寿命,这一点使Tb³⁺化合物在相同的温度范围内具有较大的温度变化范围,有助于提高其温度灵敏度。本文中,我们将合成的温度敏感探针terbium-tris[（2-hydroxy-benzoyl）-2-aminoethyl]amine化合物掺杂到PMMA基质中,制备了具有温度敏感性的含Tb³⁺化合物的薄膜,此薄膜在10-65℃温度范围内具有较高的温度敏感性,是很好的薄膜温度传感器,这在生物医药中具有潜在的应用前景。更多还原

【Abstract】 Temperature is a very key parameter in numerous fields of science and technology. Optical sensors have distinct advantages over other sensing schemes including high sensitivity, contactless operation,and inertness to even strong electrical fields.The materials doped with organic-lanthanide complexes can be used as a temperature detector and thermal-sensitive probe of an optical fiber sensor.Complexes of Eu³⁺and Tb³⁺ions have been used lately for optical sensing of temperature.Interestingly,probes for temperature based on Tb³⁺ complexes have been reported rather rarely so far,most likely because of being said not to display a highly temperature-dependent luminescence.On the other side,the Tb³⁺ion complexes predictably exhibit longer decay time than those of the Eu³⁺ion,which suggests that it would be superior to Eu³⁺ion for lifetime-based sensing of temperature.Herein,we show a temperature-sensitive film incorporating the terbium-tris[（2-hydroxy-benzoyl） -2-aminoethyl]amine complex as the probe and PMMA as the matrix,which was found to be strongly temperature sensitive（10-65℃）in both fluorescent intensity and lifetime.These properties make the film superior sensor for biological temperature sensing and imaging.更多还原
