Cr3+-Doped LiNbO3 Crystals Grown by the Bridgman Method. — LiNbO3 crysdoped with 0.1—0.5 mol% CrIII are grown from mixtures of Li2CO3, Nb2O3, and
19- 007 tals
Cr2O3 by the Bridgman method. The samples are characterized by inductively coupled
plasma spectrometry, ESR, and optical absorption and emission spectroscopy. There
are two Cr3+ centers located at Li+ and Nb5+ sites, respectively. The samples show a
broad luminescence band centered at about 932 nm. — (XIA*, H.; SONG, H.; WANG,
