The project involves the research and development of metal oxide sensor materials and sensor components. Development of the concept of design and element base of the system of non-invasive registration and signal processing by the sensor platform as an application. The idea is to synthesize nanoparticles of metal oxides and their mixtures with subsequent study of the effect of the concentration of selected gases on the intensity of photoluminescence. In order to stabilize the nanoparticles in the solid matrix, various polymers will be used to find the optimal one. Build a working device for measuring the concentration of selected gases where a UV LED will be used as a UV source, and an RGB sensor will be used to read the photoluminescence intensity, followed by digital processing to interpret the results.
