SENSITIZED FLUORESCENCE

Abstract

The quenching of mercury resonance fluorescence by thallium in a mercury-thallium vapor mixture has been measured to determine the quenching cross section of thallium for the 63 Pl) state of mercury. The measurements for the quenching cross sections at 800, 850, and 900 degrees were 34 + or -13, 31 + or-8, and 25 + or -6 square Angstrom units respectively. The cross sections for the transfer of energy to several of the thallium excited states on collision of ground state thallium atoms with excited and metastable mercury atoms were determined by measurement of the relative intensities of thallium sensitized fluorescence radiation to mercury resonance fluorescence radiation. The implications of the magnitudes of these cross sections on the prospects for the use of a mercury -thallium vapor in a laser system are discussed.
