Abstract:

Ultrasonic experiment was done at the frequency of 54 MHz on ZnSe:Cr(2+) crystal with concentration of the dopand 3.8 x 10(18) cm(-3). Giant peak of attenuation of slow shear wave propagating along (110) crystallographic direction was observed at low temperatures (about 13 K). The Peak proved to be due to relaxation process in the Jahn-Teller system. Magnitude of the peak is proportional to the concentration of the dopand. This circumstance forms the basis for a new non-destructive method of characterization of the diluted crystals, which particularly could be useful for determining the low concentration of the Jahn-Teller ions. Estimation showed that the concentration of the dopand an be registered in ZnSe:Cr(2+) crystal of the order of 10(16) cm(-3). Other Jahn-Teller ions prospective for such characterization are suggested. (C) 2010 WILEY-VCH Verlag GmbH \& Co. KGaA, Weinheim
