ELECTRON SPIN RESONANCE OF PHOSPHATE GLASSES IMPLANTED WITH 95Mo1+ IONS

Abstract

Phosphate glasses containing 50 mol% P2O5 were synthesized in various redox conditions. Molybdenum was introduced into the glass in the form of small impurities (≤ 1 wt % MoO3) with a natural content of its isotopes, as well as by implanting 95Mo1+ ions. Optical and electron spin resonance (ESR) spectra were measured. Two types of ESR spectra were observed: a singlet axial-symmetric spectrum with spin-Hamiltonian parameters: gII = 1,876, g^ = 1,930 and a spectrum with a hyperfine structure with the following parameters: gII = 1,889, g^ = 1,924, AII = 87,5×10-4cm and A^ = 40,5×10-4cm.
