FUNDAMENTAL INVESTIGATIONS OF LUMINESCENT MATERIALS.
Abstract
The main purpose of the research was to study the fundamental processes occurring in luminescent materials after the primary act of energy absorption. A second objective was to search for new luminescent substances of possible technological importance guided by the criteria established by concomitant fundamental studies on energy transfer. Numerous complexes of ruthenium(II), cobalt(III), osmium(II), iridium(III), rhodium(III), and platinum(IV) having pi-conjugated ligands were studied spectroscopically. Many of the materials were discovered to be highly-efficient, photochemically-stable, luminescent substances. Some of them exhibit properties which suggest potential value as active materials for electrooptical and laser devices. General experimental criteria were formulated which can be used to aid significantly in the task of making state assignments for new liminescent complexes of transition metals. Triplet states in rhodium complexes which are inaccessible by absorption measurements were located experimentally via emission spectroscopy. (Author)
