Optical absorption and emission of Ni-doped (80-x)Sb2O3-20K2O-xMoO3 glasses

New antimony oxide glasses were synthesized by the conventional method in the ternary system (80-x)Sb2O3-20K2O-xMoO3 (x = 30 and 40 mol%) doped with 0.1 mol% of NiO. The optical absorption spectra of Ni-doped glasses in the spectral range 750-900 nm consist of two maxima around 780 and 850 nm that a...

Summary:New antimony oxide glasses were synthesized by the conventional method in the ternary system (80-x)Sb2O3-20K2O-xMoO3 (x = 30 and 40 mol%) doped with 0.1 mol% of NiO. The optical absorption spectra of Ni-doped glasses in the spectral range 750-900 nm consist of two maxima around 780 and 850 nm that are related to Ni2+ in the octahedral environment. The maxima intensity decreases with increasing Sb2O3 and decreasing MoO3. The Condon-Shortley parameters F0, F2 and F4 have been used to determine the crystal field parameters of Ni2+ in these glasses. Racah's parameters have also been calculated. Visible emission at 560 nm has been obtained at room temperature.
