Resonance Transfer of Electronic Energy in Organic Crystals

Abstract

The resonance transfer of energy in crystals of organic compounds when excited by visible or ultra-violet light has been examined by measuring the fluorescence of the systems naphthalene-anthracene, anthracene-naphthacene, naphthacene-pentacene, anthracene-acridine, anthracene-phenazine, and anthracene-di- and hexabromobenzenes. The conditions for " exciton " trapping and the relations of resonance transfer to fluorescence quenching are discussed.
