Due to the fact that magnetic fields are ubiquitous in our world, spin polarized atomic magnetometers are used in a wide range of applications from the detection of magnetic fields generated by the human heart and brain to the detection of nuclear magnetic resonance.
Luminescence type gas sensors based on organic luminophores are characterized by an excellent signal stability over the luminophores' lifetime. Even though the sensing material is prone to degradation due to photobleaching, evaluation of the dynamic optical response allows to minimize aging induced drift effects of the luminophore and the optoelectronic components. The gas dependent luminophore decay time is mostly independent of the excitation intensity, which is attributed to the monomolecular recombination in many organic luminophores. To improve the overall sensor lifetime and to utilize this luminescence based sensor concept for long-term sensing applications, new luminophores are needed. Potential candidates are inorganic, semiconducting materials, which, however, show more complex recombination behaviour than the organic luminophores mentioned before, involving also bimolecular recombination.
