For fluoroaluminate glass (FAS-36) based on usovite mineral implanted with
Ti+ (E = 150 keV, D = 2 x 10(16) cm(-2)) EPR line at g = 1.944 and optical
absorption band at similar to 475 nm were assigned to Ti3+ ions in compress
ed octahedron. In EPR spectrum of FAG-36 coimplanted with Ti+ and F+ the tr
iplet centered at g similar to 1.935 with the splitting of 1.1 mT is attrib
uted to TiF2+ molecular ions. (C) 2001 Elsevier Science B.V. All rights res
