Zur Kenntnis der optischen Aufheller II: Physikalische und chemische Vorgänge bei der Fluoreszenzlöschung und optischen Filterwirkung

The Optical Brighteners II. The Physical and Chemical Processes of the Fluorescence Extinction and the Optical Filter Effect The fluorescence extinction of the optical brighteners is an undesirable phenomenon in case of white textiles. There are different causes which can lead to the fluorescence extinction. The effect is shown in the statical or dynamical extinction mechanism or in an optical filter effect. It is also possible to depict the fluorescenceinfluence through the principle of self or extraneous extinction. The present work discusses the processes of fluorescence extinction and its form of appearance. The optical filter effect is also discussed.
