| Popis: | Er(3+)-singly doped and Er(3+)/Yb(3+)-codoped 50SiO2-(50-x)BaF2-xZnF2(SBZx) oxyfluoride glasses are prepared and the optical properties of Er(3+)-singly doped glasses are investigated by using the Judd-Ofelt theory. Bright green and red upconversion luminescence of Er(3+)/Yb(3+)-codoped glasses is obtained under 980nm excitation. Furthermore, factors affecting this phenomenon such as glass composition, doping concentration of Er(3+) and Yb(3+) ions, and pump power are discussed in details. |
