- In the article there are presented two different series of glass: fluorophosphate with molar composition: $65P_2O_5-8Al_2O_3-$ $2BaO-5BaF_2-6ZnF_2-$ $5Na_2O-$ $6MgF_2-3B_2O_3$ and antimony glasses $40Sb_2O_3-$ $3Al_2O_3-$ $57SiO_2$ doped with $Nd^{3+}$ and $Yb^{3+}$ ions. Dopant contents influence efficient spatial overlapping of emission level for neodymium and absorption level for ytterbium was analyzed. While exciting the produced glasses with a laser diode (λ = 808 nm) a broad luminescence spectrum (Δλ = 100 nm) has been obtained in both cases in the vicinity of 1 μm, being the superposition of the following transitions: $\text{}^4F_{3//2} \rightarrow {\text{}^4I_{11//2}}$ for $Nd^{3+}$ and $\text{}^2F_{5//2} \rightarrow {\text{}^2F_{7//2}}$ for $Yb^{3+}$. Based on the luminescence measurements the probability of non-radiative energy transfer was described. Because of a small difference in energy ( ≈1190 $cm^{-1}$) between the laser levels of neodymium and ytterbium the resonant process of energy transfer has been obtained.
