Fluorescent Lifetimes of Uranyl Salts at Different Temperatures

Not Accessible

Your library or personal account may give you access

Abstract

The decay of the fluorescence of uranyl salts has been measured at 293°, 77°, and 4°K with a photoelectric gate circuit technique. The resultant mean lives of the excited states in general increase sharply with decreasing temperatures. This indicates that at the higher temperatures where relaxation times as low as 50 microseconds are found the upper states are destroyed chiefly by interaction with the crystal lattice. The lifetime of the undisturbed UO2 ion must be more than 2 milliseconds. This is in agreement with the brightness of the fluorescence which normally increases in proportion with the mean life.
