【摘要】 近年来,由于众所周知的国家安全和环境问题的需要,危险化学品的痕量探测成为近年来关注的焦点。荧光传感技术尤其是荧光共轭聚合物由于其灵敏度高、选择性好、响应快等受到广泛关注。通过特殊的化学反应、能级调节和形貌控制等合成了系列的高性能传感材料。以取向性纳米线阵列为基底,利用倏逝波等效应,实现了弱光激发信号放大,提高了传感性能,制备了高性能荧光传感器件。更多还原

【Abstract】 Trace detection of dangerous chemicals have attracted wide attendtion for homeland security and environmental problems. Fluorescent sensory material especially fluorescent conjugated polymerhas become the focus due to its high sensitivity, selectivity and quick response. Serial sensory materials with high performance were synthesized via special chemical reaction, energy level tuning and morphology control. And utilizing the envanescent wave effect of the nano rod, the fluorescent signal was magnified to afford highly sensitive devices.更多还原
