IMPLANTATION OF COBALT INTO OXIDE GLASSES
Abstract
Oxide glasses were implanted with Co+ ions at nominal fluences (F) ranging
from 2?e1015 to 3?e1017 cm-2 at energy E = 150 keV. The lines of EPR with g ~ 4 were observed
at 4.2 K for the samples implanted to F = (2?i8)×1015 cm-2 and were attributed to
Co2+ ions in distorted octahedral or tetrahedral environment depending on substrate. Results
of TEM, optical spectroscopy and EPR indicate the formation of Co metallic nanoparticles
at F >1016 cm-2. FMR line with g ~ 2.2 was observed in temperature region 4.2
?i77 K and even at 295 K for silicate glass.
