An optical waveguide sensor using an intermediate layer between the preformed optical core and the optical cladding material. This intermediate layer comprises a material that is doped with a sensor material to respond to an analyte of interest by luminescing or by developing optical absorption in the transmission region of the core fiber and that has a refractive index greater than the preformed core. Two configurations provide sensors for ionizing radiation capable of measuring the dose rate and the integrated deposited dose.

A process for treating metal surfaces to obtain improved susceptibility to bonding with adhesive compositions is disclosed. A metal surface is oxidized with a halogen to form a monolayer of halide ions on the surface. The halide ions are then exchanged with azide ions to form an azide monolayer on the metal surface. Upon contact of the treated surface with an adhesive composition, the azide layer may be thermally or photochemically decomposed to form active nitrene species, which react to bond the adhesive composition to the metal surface.
