摘要: The upconversion properties of Er3+-doped heavy metal oxyfluoride germanate glasses under 975\,nm excitation have been investigated. The intense green (551 and 529\,nm) and relatively weak red (657\,nm) emissions corresponding to the transitions 4S3/2 \to 4I15/2,2H11/2\to 4I15/2 and 4F9/2 \to 4I15/2, respectively, were simultaneously observed at room temperature. The content of PbF2 has an important influence on the upconversion luminescence emission. With increasing content of PbF2, the intensities of green (529\,nm) and red (657\,nm) emissions increase slightly, while the green emission (551\,nm) increases markedly. These results suggest that PbF2 has an influence on the green (551\,nm) emission more than on the green (529\,nm) and red (657\,nm) emissions.
