It is observed that the transition lifetime increases from 116μs to 2.Keywords: Inhomogeneous broadening; Optical lifetimes; Potential materials; Quantum memories; Residual hydrogen; Deuterium; Hydrogen; Linewidth EuCl 3 · 6D 2O; Optical lifetimes; Quantum memoryOptical lifetime and linewidth studies of the 7F0 - 5D0 transition in EuCl3 6H2O: A potential material for quantum memory applications201310.1016/j.jlumin.2011.12.0362016-02-24
