Abstract: | A line of the GdIII ion was detected at 311 nm in the multibubble sonoluminescence spectrum of a concentrated (1 mol L−1) solution of gadolinium chloride. A comparison with the earlier studied sonoluminescence of the CeIII and TbIII ions shows that the GdIII ion is excited in the volume and/or on the surface of cavitation bubbles upon collisions with “hot” particles. The efficiency
of excitation of the lanthanide ions via this mechanism depends on the type of electron transition. For the same energy of the excited state, the efficiency of GdIII excitation (f-f transition) exceeds by at least 50 times that of CeIII excitation (f-d transition).
