EPR of fluoroaluminate glasses implanted with titanium

Abstract For fluoroaluminate glass (FAG-36) based on usovite mineral implanted with Ti + ( E =150 keV, D=2×10 16 cm −2 ) EPR line at g =1.944 and optical absorption band at ∼475 nm were assigned to Ti 3+ ions in compressed octahedron. In EPR spectrum of FAG-36 coimplanted with Ti + and F + the triplet centered at g ∼1.935 with the splitting of 1.1 mT is attributed to TiF 2 + molecular ions.
