Direkte Konzentrationsabhängigkeit der Fluoreszenz einer Haupt- und einer Nebenlinie des Rubins

Abstract

The concentration dependence of theR-lines of ruby shows three characteristic regions: The first has the expected linear increase of emission intensity with increasing concentration; the second shows a weaker increase than linear and is explained by the assumption, that energy is distributed more to nebenlines; the third shows a rapid decrease of the emission as is expected for quadrupole-quadrupole interaction between the active atoms.

The emission of theN ₂-line of ruby increases nearly quadratically with increasing concentration and decreases in the third region as fast as theR-lines.
