The introduction of luminescent materials into a sol–gel-derived silica layer is a promising way for the creation of optical applications on the basis of UV-sensitive waveguides. In this work, the preparation of tetraethylorthosilicate (TEOS)-derived silica layers doped with terbiumtrisbenzoate is described. Results with respect to the layer thickness, the photoluminescence of doped bulk silica materials...
Since glassfibres are a common method for transport of information, this study examines the application of glassfibres in UV sensors. To this end, the glassfibres have been coated with a silica-xerogel doped with lanthanide carboxylate complexes, especially terbium picolinate (TbPic). Different pretreatments of the glassfibres have been tested in order to enhance the signal to background ratio of...
