Growth And Spectroscopic Investigation Of Ndcl3 Center Dot 6h(2)O Crystal

Rare-earth-ion-doped crystals have been a promising candidate material for optical quantum memory, which is the fundamental building block for quantum networks. The unwanted broadening caused by rare-earth dopants can impose limits to the available absorption in the doped crystals. To solve this problem, stoichiometric rare-earth crystals have been considered, such as EuCl3 center dot 6H(2)O crystal, whose inhomogeneous broadening is measured to be 25 MHz with an extremely strong absorption. Stoichiometric rare-earth crystals that contain Kramers ions could further fulfill the requirements for broadband quantum storage and interfacing with microwave photons. Here we grow NdCl3 center dot 6H(2)O single crystals and perform optical absorption and emission spectroscopy of this material. (C) 2021 Elsevier B.V. All rights reserved.
