Spectroscopic study of neodymium-doped LilnS2 single crystals

摘要

Abstract: Nd-doped LiInS$-2$/ single crystals were grown using the Bridgeman technique and their optical properties studied. An intense emission with a dominant line at 1077 nm and groups of lines centered at 600, 760, 820 and 890 nm in absorption/luminescence excitation spectra are related to Nd$+3$PLU$/. Doping results in a considerable increase of broad band absorption in the 400 - 460 nm range and a blue emission line at 440 nm at 80 K. Both are associated with transitions between In$-Li$/ level and valence band.!3
