摘要	The paper proposed a new determination method to meet practical needs of trace detection of dissolved oxygen (DO), which is based on fluorescence quenching and using holy optical fiber (HOF). A DO optical probe was fabricated by modifying the sensitive film doped with fluorophore in the array microholes of HOF, and the sensing character was characterized. The microholes throughout the whole fiber could be used as the substrate of sensing materials and minor reaction pools. Compared with the conventional DO probe, the arrays microholes had huge sensing surfaces and the fluorophore can interact directly with the oxygen molecules, so the sensitivity was improved and also has the potential application in microanalysis detection. From the experimental results, we find the Stern-Volmer plots are linear in the full concentration range of 0~20 mg/L. The ratio of I0/I as a sensitivity of the probe is 3.6, and the probe can make a quick response within 200 ms. The probe has important applications in the dissolved oxygen trace detection.
