Luminescence spectroscopy of rare earth-doped oxychloride lead borate glasses

►Lead borate glasses modified by PbCl2 were synthesized. ►Luminescence of Pr3+, Tm3+, Eu3+ and Er3+ ions in multicomponent oxychloride glasses was registered. ►From decay curves luminescence lifetimes for the excited states of rare earth ions were determined. ►The relatively high phonon energy of the host gives important contribution to the excited state relaxation of rare earth ions.
