LIQUID LASER PARAMETERS
Abstract
The results of a series of phosphorescence lifetime and intensity measurements on rare-earth coordination compounds are given and discussed. Enhanced phosphorescence has been observed in scrupulously anhydrous systems and the means of preparing such salts is described. The role of ligand vibrations in influencing nonradiative decay from excited levels is analyzed. Experiments with europium(III) in selenium oxychloride have lead to a hypothesis that it is critical to enhance nonradiative decay from excited levels to the emitting level. The need and means for improving the lifetime-measuring apparatus is presented along with planned modifications of the spectrophotofluorometer to allow measurements in the infrared region of the spectrum. Photochemical transformations in a particular europium(III) complex are noted.
