Resumo

Er3 +-singly doped and Er3 +/Yb3 +-codoped 50SiO2–(50 − x)BaF2–xZnF2(SBZx) oxyfluoride glasses are prepared and the optical properties of Er3 +-singly doped glasses are investigated by using the Judd–Ofelt theory. Bright green and red upconversion luminescence of Er3 +/Yb3 +-codoped glasses is obtained under 980 nm excitation. Furthermore, factors affecting this phenomenon such as glass composition, doping concentration of Er3 + and Yb3 + ions, and pump power are discussed in details.
