Abstract: The invention relates to a fluorescent siloxane elastomer, to a method for producing same, and to the use. The fluorescent siloxane elastomer contains the following structural elements in the network structure thereof: (I) and (II) or (III), wherein: R1 and R2 are the same or different and mean, independently of each other, a methyl, phenyl, vinyl substituent or an H atom; X means a saturated or unsaturated hydrocarbon group having 2 to 6 C atoms; A is an oxygen, nitrogen, or sulfur atom; R3 is a fluorescent dye substituent from the families of the BODIPY or BODIPY and coumarin or BODIPY and naphthalimide or coumarin and naphthalimide fluorophores. The polysiloxanes according to the invention cause a shift in the emission range out of the UV light or expansion of the emission range into the range of visible light having wavelengths of up to 800 nm, and therefore the polysiloxanes are especially suited for detectors having the maximum efficiency thereof in the range.

Abstract: A high-voltage device for receiving a high-voltage cable having a conductor designed to conduct an electrical current and a cable insulation surrounding the conductor, includes an insulation and a waveguide. The insulation includes an at least partly transparent or translucent field control unit from a siloxane polymer which is designed to at least partly surround the cable insulation of the high-voltage cable, the siloxane polymer including, in at least one portion of the field control unit, covalently bonded fluorophores and/or dielectric pigments. The waveguide is arranged such that a light signal caused by a partial discharge in the field control unit can be coupled from the field control unit into the waveguide.
