    • The invention relates to an optochemical sensor (1) comprising a polymer matrix which is applied to a substrate (4) and which is doped with a luminescent colorant, the emissivity of which can be modified after excitation with electromagnetic radiation by substances to be detected such as gaseous or dissolved O
      2 , SO
      2 , H
      2 O
      2 , CO
      2 , nitrogen oxides and halogenated hydrocarbons, which polymer matrix forms a sensor layer that is also covered by an optical insulating and protective layer (7) which can be permeated by the substance to be analysed. In the optochemical sensor, the sensor layer is formed from a layer which has an insular sensor element or a plurality of mutually separated sensor elements (2), the at least one sensor element (2) being covered by a non-doped polymer matrix (3) which chemically corresponds to the polymer matrix of the sensor layer.
    • 本发明涉及包含聚合物基体的光化学传感器(1),所述聚合物基体应用于基板(4)并掺杂有发光着色剂,其发射率可在用待检测物质激发电磁辐射后改变 作为气态或溶解的O 2,SO 2,H 2 O 2,CO 2,氮氧化物和卤代烃,该聚合物基质形成传感器层,该传感器层也覆盖有光学绝缘和保护层(7) 要分析的物质。 在光化学传感器中,传感器层由具有岛状传感器元件或多个相互分开的传感器元件(2)的层形成,所述至少一个传感器元件(2)被非掺杂聚合物基体(2) 3),其化学对应于传感器层的聚合物基体。
