optical methods to measure the oxygen concentration and the optical sensor for measuring oxygen concentration

摘要

the invention provides an optical method of measuring an oxygen concentration and an optical sensor for measuring an oxygen concentration, and a light absorbing farbstoffmolek & t.; lschicht whose absorption spectra in abh & auml; in response to the binding with and ffmolek & t.; len & auml; look at, combined with light emitting layerand the oxygen concentration of umgebungsfluid can be measured.the light absorbing layer (4), the light emitting layer in an oxygen abquenchenden (3) laminated, a film, a cobalt porphyrin complex (cop) or other light absorbing farbstoffmolek & t.; l (7) in the absorption spectra in abh & auml; ngig activity of binding with sauerstoffmolek & t.; len & auml; look at.if the berdeckungsgrad and professional; the lichtemissionsspektrum or excitation (absorption) spectrum of the light emitting layer (3) as a result of a & auml; and in the absorption spectra and auml; look at the light absorbent layer (4) is made, and auml; look at it the lichtintensit & auml; t of ausgangslicht according to the berdeckungsgrad, and professional;and the oxygen concentration of the umgebungsfluids can be measured. the me & white; method and the me & white; sensor k & all; not only in optical fasersensoren can, but also in the model, and try auml;. a pressure-sensitive colorants to be used.
