Description

Verfahren zum Nachweis von ultraroten Strahlen Zusatz zum Patent 939 233 Gegenstand des Hauptpatents 939 233 ist ein Verfahren zum Nachweis von ultraroten Strahlen, bei dem ein Absorbens durch auffallende Wärme strahlung zur Abgabe eines von ihm aufgenommenen Stoffes veranlaßt wird, der dann auf einen Leuchtstoff einwirkt und diesen zum Aufleuchten bringt. Dieser Vorgang verläuft bei abnehmender Wärmestrahlung wieder umgekehrt. Es werden hier nur Leuchtstoffe verwandt, die durch Zufuhr eines Stoffes aufleuchten, wie es z. B. bei der Einwirkung von Sauerstoff auf die Extrakte von Leuchttieren der Fall ist.Method for the detection of ultra-red rays Addition to patent 939 233 The subject of the main patent 939 233 is a method for the detection of ultra-red Radiation, in which an absorbent by incident heat radiation to give off a is caused by it absorbed substance, which then acts on a phosphor and makes it light up. This process takes place with decreasing thermal radiation reversed again. Only phosphors are used here that are produced by adding a Light up the fabric, as it is z. B. in the action of oxygen on the extracts of luminous animals is the case.

Zur Verbesserung dieses Verfahrens werden gemäß der Erfindung Leuchtstoffe benutzt, deren Lumineszenz unter der Einwirkung von Gasen, Flüssigkeiten oder Dämpfen, je nach dem Druck derselben, teilweise oder vollständig verschwindet. To improve this process, phosphors are used according to the invention used whose luminescence under the action of gases, liquids or vapors, depending on the pressure of the same, partially or completely disappears.

Die Verwendung derartiger Leuchtstoffe macht das Verfahren zum Nachweis ultrarotef Strahlen äußerst empfindlich.The use of such phosphors does that procedure extremely sensitive for detection of ultrarotef rays.

Bei der praktischen Ausführung der Erfindung können Leuchtstoffe mit diesen Eigenschaften in Form von Lösungen verwandt werden oder man benutzt anstatt der Lösungen Systeme, in welchen die Moleküle von Leuchtstoffen in geringer Konzentration an geeigneten Oberflächen durch Adsorption festgelegt sind. Hierbei ist die Anwendung der Leuchtstoffe auf letztere Art, nämlich die Benutzung von Leuchtstoffadsorbaten, besonders günstig, da hierdurch ein besonders helles Leuchten -und eine größere Lebensdauer erreicht wird. Da die Lebensdauer derartiger Leuchtstoffe, d. h die Dauer der Lumineszenz, begrenzt ist, muß eine solche Zelle von Zeit zu Zeit kurz belichtet werden. In practicing the invention, phosphors can be used with these properties in the form of solutions or used instead of the solutions systems in which the molecules of phosphors are in low concentration are fixed on suitable surfaces by adsorption. Here is the application of the phosphors in the latter type, namely the use of fluorescent adsorbates, particularly favorable, as this results in a particularly bright glow - and a larger one Service life is reached. Since the life of such phosphors, i.e. h the If the duration of the luminescence is limited, such a cell must be short from time to time to be exposed.

Von den Leuchtstoffen mit den gewünschten Eigenschaften kann z. B. Trypaflavin oder Uranin, ein lösliches Fluoreszin, verwandt werden, die speziell empfindlich gegen Sauerstoffeinwirkung sind. Of the phosphors with the desired properties, e.g. B. Trypaflavin, or uranine, a soluble fluorescein, is specifically related are sensitive to the effects of oxygen.
