Аннотация
Currently, fluorescent sensors for detection of explosives are being actively developed. One of the important issues, along with the sensitivity and speed of analysis, is the stability of the fluorescence of a sensitive luminophore, and the natural degradation of its fluorescence under the action of exciting radiation. In this work, we study the fluorescence response of MDMO-PPV embedded in a porous silicon microcavity to trinitrotoluene vapors under the action of exciting radiation with different intensities and wavelength of 450 nm. The conclusion is made about the preferred mode of the luminophore excitation. © 2022 IEEE.
