基于芘丁醇的光学压敏涂料氧猝灭特性

Oxygen Quenching of the 1-pyreny1 Butanol-based Pressure Sensitive Paints

以芘丁醇为原料制备的光学压敏涂料作为研究对象，采用荧光分光光度计测定了它们的荧光特性，考察不同激发光波长下压敏涂料的荧光特性及氧猝灭系数。结果表明：以芘丁醇为原料制备的压敏涂料的氧猝灭效果明显，其氧猝灭系数高达55％。涂料的荧光特性受激发光波长的影响很大，就同一受激态发射区464nm峰而言，用290nm的激发光比用364nm的激发光的氧猝灭率高出21．3％。

In this paper, the 1 - pyrenyl butanol-based pressure sensitive paints are used as the research object. Fluorescence characteristics are measured by fluorophotometer, fluorescence characteristics and oxygen quenching coefficient are studied on different excitation spectra of pressure sensitive paints. The results show that the effect of the oxygen quenching coefficient to the 1 - pyrenyl butanol-based pressure sensitive paints is obvious. It can reach 55% of the coefficient. The excitation spectra have a strong effect on the fluorescence characteristics, as the same number of 464 nm to the excimer emission. The oxygen quenching of using the 290 nm excitation is 21.3% more than that of using 364 nm fluorescence.
