Over the last decades, luminescence quenching has been established as a widespread technique for gaseous oxygen monitoring in a broad range of applications. Thus, considerable effort has been made to manufacture luminescent oxygen sensors. The performances of such sensors are determined by the oxygen indicator and the matrix that entraps this indicator as well. In spite of its versatility for fine-tuning the final features of nanostructures, the Layer-by-Layer nano-assembly technique has been rarely studied for fabricating these sensors. This could be explained by the fact that most of the optically stable and highly sensitive oxygen indicators are not water soluble. The main objective of this work is to combine these detection and deposition techniques with optical fiber setups, for the fabrication and characterization of luminescent optical fiber oxygen sensors fabricated by Layer-by-Layer nano-assembly.
