文摘
The Tb3+/Yb3+ co-doped lithium borate (LB) glass prepared by melt quench method. The Tb3+/Yb3+ co-doped glass gives QC emissions upon 266 and 355 nm excitations. The Tb3+/Yb3+ co-doped glass also emits intense green color on excitation with 976 nm. The quantum cutting efficiency is larger for 355 nm excitation (137%). The Tb3+/Yb3+ co-doped glass may be used in solar cell and display devices.
