Paper Abstract

The new dye which has improved spectral characteristics synthesized on the basis of platinum complex of the porphyrin-like compound was studied with the view of its application to oxygen sensing. It resulted in a new solid-state oxygen-sensitive material with advanced working characteristics which is highly compatible with excitation with yellow LEDs. This new sensing material makes it possible to develop simple fiber-optoelectronic devices -- prototype oxygen sensors. One of the embodiments was constructed which utilizes powerful yellow LED as a light source, silicone photodiode as a photodetector, and has a fiber-optic output terminated with an active element (oxygen membrane). The electronic scheme of the device provides modulation of LED at a kilohertz range frequency and is capable of measuring specific luminescent signal. The system is now under improvement and optimization with emphasis to lifetime measurements performed by phase method.
