LIQUID LASER PARAMETERS
Abstract
Attempts have been made to extend the calculation of energy-flow diagrams to a series of additional europium(III) complexes. This has led to the appearance of negative rate constants, a physically impossible result. The equations and assumptions which describe the system are reviewed, and a possible improved approach is described. It has been ascertained that previous assumptions could be eliminated if one additional variable could be measured. A prime possibility is the steady-state population of the emitting level. A feasible manner of measuring such a quantity appears to be electron paramagnetic resonance. A recalibration of the fluorescence-measuring apparatus has been performed, and several modifications introduced which have increased the accuracy of the measurements. Fluorescent spectra of a number of terbium(III) complexes have been obtained. These data reveal that for terbium, as for europium, the alkyl phosphate complexes are the most promising for laser applications.
