摘要：

An optical oxygen-sensing material based on the fluorescence intensity changes of pyrene-1-butyric acid (PBA) chemisorption film has been developed and characterised. The fluorescence intensity of PBA film decreased with increase of oxygen concentration. The I-0/I-100 value of PBA film is estimated to be 6.14 +/- 0.15 and large Stern-Volmer constant (K-SV = 0.028 +/- 0.13 Torr(-1)) is obtained. After it-radiation for 24 h with 150 W tungsten lamp, little changes of oxygen-sensing properties were observed. These results indicate that PBA film is highly oxygen-sensitive and photostability device. The response times of the PBA chernisorption film were 10.0 s fur switching from argon to oxygen, and 53.0 s for switching from oxygen to argon. Moreover, the optical sensor based on the PBA chemisorption film was applied to the measurement of oxygen concentration in aqueous solution. (C) 2002 Elsevier Science B.V. All rights reserved.
