FLUORESCENT SPECTRA OF SOME ORGANIC SOLID SOLUTIONS

A method to measure the spectral distribution of the luminescence of solids is described. Use is made of a spectrophotometer in combination with a photo-multiplier tube. Spectra have been investigated and discussed for solid solutions of naphthacene and 1,2,5,6–dibenzanthracene in naphthalene and anthracene as functions of concentration.
