A spectroscopic study of BaY₂F₈: Nd³⁺

Absorption and fluorescence measurements at low temperature were used to obtain an energy level scheme for the Stark components of the Nd3+ manifolds in BaY2F8 up to 40 000 cm-1. The fluorescence lifetimes of the 4F3/2, 2P3/2, 4D3/2, and 2F(2)5/2 levels were also measured between helium and room temperatures. © 1991.
