Polymethine Dye as Sensors of NH3 and CO

الملخص EN

We have investigated the properties of polymethine dyes (PMD) and the purpose of using them as sensors of hazardous gases presence.

Research indicates that in case of utilizing PMD as a sensor of hazardous gases we need to use the monochromatic light which wavelength corresponds to the inflection point of the long-wave absorption edge of PMD.

Such sensor of hazardous gases can detect changes in the optical density of the sensor layer or the light intensity transmitted through the layer.
