Abstract: The present invention pertains to an optical sensor for detecting gaseous or liquid chemical species which comprises a sensing element having a thin film and means of measurement by interference enhanced reflection. The sensing element comprises preferably a flat light reflecting substrate and one or more transparent thin organic or inorganic films or high-polymer films that are formed on said substrate. The detection of the gaseous or liquid chemical species is effected by measuring the change in the light reflection characteristic of the sensing element on the basis of the swelling of the thin film or the change in its thickness or refractive index or the changes in both parameters. The invention concerns also an apparatus including such optical sensor for detecting the presence of a toxic, combustible or flammable gas, vapor or solvent, an alarm and/or a means of running on and off switches or pipelines.

Abstract: The invention concerns the use in electroluminescent devices of heterospiro-compounds of formula (I), in which PSI means an element of the fourth main group of the periodic system of elements, with the exception of carbon, and is preferably Sn, Ge or Si, particularly preferably Ge or Si, and K and K , independently of each other, mean conjugated systems. The compounds of formula (I) are distinguished by good solubility in common organic solvents, improved film-forming properties and a considerably reduced tendency towards crystallization.

Abstract: Method of making optical materials from silicon nitride by pyrolysis of polymeric silazanes by pressing, before the pyrolysis, the pulverulent polymeric silazanes to give mouldings or first dissolving the polymeric silazanes in an organic solvent, drawing fibres from this solution and pyrolysing said fibres after evaporation of the solvent or by melting of polymeric silazanes, casting, injection-moulding or extruding this melt to give mouldings and subsequent pyrolysis. During or after the pyrolysis, an oxidic layer is produced in an oxygen-containing atmosphere on the silicon nitride moulding. The pyrolysis can be carried out at 800-1000 DEG C in an atmosphere containing ammonia or containing ammonia/inert gas mixtures.

Abstract: Process for manufacturing an optical coupler for polymer light-guides with the aid of the ultrasonic welding technique. The fibres (2, 6) are heated to a temperature of 50 to 250 DEG C for 0.2 to 3 hours before welding. The polymer light-guides are introduced into a small plastic tube (5), which during the welding operation fuses with the said light-guides to form a unit. In another embodiment, a mixer rod, which has the same refractive index as the core material of the polymeric optical fibres, can be introduced into the small plastic tube (5), the polymeric optical fibres are brought into contact with it and the small plastic tube, the mixer rod and the fibres are welded to one another under the effect of ultrasound. … …

Abstract: Measuring device for the determination of the concentrations of inorganic and organic compounds in a sample, with a sensor which is to be brought into contact with the sample and which contains a fluorescence-optical indicator which after excitation via an excitation light source fluoresces as a function of the present concentration of the inorganic or organic compound to be detected. The measuring device has an arrangement for measuring and analyzing the incident radiation and the re-emitted fluorescence light. The measuring device contains a sensor element which is to be brought into contact with the sample and consists of a polymer matrix which is prepared from a) a matrix component which is derived from one or more units of the formula I where R - is hydrogen, deuterium or methyl; R - and R -, independently of one another, are hydrogen, deuterium or methyl, and the degree of polymerization, n is an integer in the range from 80 to 2500, preferably from 200 to 2000; b) a dye component which is immobilized covalently on the acyl chloride groups of the matrix component and c) one or more swelling components which are bound covalently to the remaining free acyl chloride groups of the matrix component.
