Abstract

Bulk single crystals up to 20 mm in diameter and 40 mm long for LiInS₂ and up to 10 mm, 20mm, respectively, for LiInSe₂ have been grown. Their color changed from colorless to rose for the first one and from yellow to dark red for the other. All crystals have wurtzite-type lattice, lattice parameters were determined. A band gap was found to be 3.72 and 3.57 eV for LiInS₂ and 3.02, 2.86 eV for LiInSe₂ at 80 and 300K respectively. Color variations are due to point defects, first of all to interstitial sulfur, resulting in additional wide absorption bands in the shortwave part of transparency range. For LiInS₂ the SHG phase matching conditions were found to be similar for samples of different color and some difference from Boyd's predictions of 1973 was shown.
