METHOD AND DEVICE FOR PRODUCING SINGULET OXYGEN

摘要

The invention relates to a device for producing singlet oxygen, comprising a housing forming a chamber which has at least two opposite surfaces. One of said surfaces is transparent and the other is covered by a coating made from a dye excitable by light, and a light source for irradiating the surface covered with the dye. The surface covered with the dye is formed by a substrate comprising a finely roughened surface. The dye is introduced into the indentations of the finely roughened surface by polishing. The light source can be formed by light emitting diodes, whose light emission comprises a wavelength located within the range of maximum radiation absorption of the dye of the coated surface.
