Examination of various shape of sol-gel optodes for indirect fiberoptic sensors
Abstract:Abstract: The sol-gel derived matrices for indirect fiberoptic sensors are described. Variously shaped fiber tips with attached optodes are prepared: flat one with macroptode, as well as tapered and shallow ones with microoptodes. The angular light intensity distribution near the fiber tip was measured for these three types of optodes. Advantages and disadvantages of the above solutions are discussed. The Ruthenium complex based optodes were constructed and the sensors responses after 36 hours of constant illumination were examined, as well. The smallest signal decrease was observed for shallow fiber tip with an internal microptode.
