摘要：

The effect of substituting deuterium for hydrogen in EuCl3 center dot 6H(2)O on the lifetime and homogeneous and inhomogeneous linewidths of the F-7(0)-> D-5(0) transition at below 4 K are investigated. It is observed that the transition lifetime increases from 116 mu s to 2.6 ms and the homogeneous linewidth decreases from 4.1 kHz to 430 Hz. The sensitivity of the inhomogeneous broadening to the residual hydrogen concentration is estimated to be 91 MHz/atm%. The potential of utilizing this crystal for quantum memory applications is discussed. (c) 2011 Elsevier B.V. All rights reserved.
