Abstract. The work demonstrates the possibility of using a structure, which is similar to the structure of a powder photosensitive capacitor, as a spectrophotometric sensor. For creating an active photosensitive layer of the sensor, a suspension of ZnS:Cu:Al:Cl particles uniformly distributed in a dielectric matrix C 3 H 5 (C 18 H 33 O 3 ) 3 was used as a dielectric layer between the capacitor plates. It was shown that, depending on the characteristics of the active layer material (particle size and material, dielectric matrix properties) and the configuration of the electrical circuit, the sensor can effectively operate both in the capacitive element mode and in the voltage generator mode.

Keywords:spectrophotometric sensor, photosensitive powder capacitor, ZnS:Cu:Al:Cl particles.
