摘要: Abstract Relaxation of 1.54 μm emission the erbium doped borosilicate glasses with high rare earth solubility was investigated. When content is less than 0.2 wt%, multi-phonon relaxation predominant process non-radiative relaxation. It difficult to increase quantum efficiency higher 70% for ions in this glass due Because good glass-formation ability and solubility, will be suitable as a host large energy gap, such Yb3+, Eu3+ or Tb3+.
