Abstract:

The effects of B₂O₃ content and different modifiers (alkali metals and alkaline earth oxides)on the spectroscopic properties of Yb³⁺-Er³⁺co-doped B₂O₃-P₂O₅-MO-R₂O-AI₂O₃(M=Zn,Ca,Sr,Ba;R=Li,Na,K)system were respectively analyzed.Th e results indicate that,with the increase in B₂O₃ content,the radiation lifetime increases,while the spontaneous emission probability,the absorption cross-section,the corresponding integral absorption cross-section and emission cross-section all decrease,that the refraction index reaches its minimum when the mole fraction of B₂O₃ is 15%, and also that the absorption cross-section and the emission cross-section increase with the electric field intensity of the modifier cation.
