Absorbent structure, particularly a sensor, provided with a thin film layer of not monomeric phtalocyanine and/or phtalocynine derivatives and a method for regenerating it

摘要

This invention relates to an absorbant structure (2) comprising a sensitive component (3), provided with a thin film layer of not monomeric phtalocyanine and/or phtalocyanine derivatives, and a light source (5), arranged in such a position as to be adapted to irradiate said thin film layer of the sensitive component (3), the thickness of said thin film layer being not greater than 100 nanometers, said light source emitting light having a wavelength in the range of 180 to 600 nanometers. The invention also relates to a regeneration process for said absorbent structure (2).
