文摘

In the present work, the optical properties of Sb³⁺-doped and Sb³⁺/Eu³⁺ co-doped phosphate glasses were investigated. The blue emission intensity of Sb³⁺ decreased significantly while the red emission intensity of Eu³⁺ increased with the increasing concentration of Eu³⁺ ions. It was confirmed that an energy transfer from Sb³⁺ to Eu³⁺ occurred and the possible luminescent mechanism was proposed. The results suggest that the sensitization of Sb³⁺ not only enhance the emission intensity of Eu³⁺ excited at 274 nm, but also results in the tunable emission color of the glasses. Particularly, white light photoluminescence combining blue and red emission was observed under ultraviolet light excitation.
