Laser Induced Fluorescence In Uranium-Doped Glass

Two fluorescent levels were observed in a soda-lime-silica glass containing 1% uranium at 5145 and 5242 A. There is a possibility of a third fluorescent level at 5180 A. The emission peaks are attributed to the transitions from the fluorescent levels to the symmetric and antisymmetric modes of the ground state of the uranyl ion. The intensities of the fluorescent systems are dependant on the excitation wavelengths of the argon ion laser and the sample temperatures.
