Effects of the site symmetry and host polarizability on the hypersensitive transition (super 3)P(sub 0) -> (super 3)F(sub 2) of Pr3+ in fluoride glasses

Research was conducted to examine the effects of the site symmetry and host polarizability on the hypersensitive transition (super 3)P(sub 0) -> (super 3)F(sub 2) of Pr3+ in fluoride glasses. A comparison of the data in fluoride families and the date on the selected tellurite and sulfide glasses was performed. Results show that the (super 3)P(sub 0) -> (super 3)F(sub 2) transition of Pr3+ in fluoride glasses hosts is hypersensitive. The effect of ligand (glass host) polarizability on this hypersensitive transition within fluoride glass families was also demonstrated.
