Opis:: The infrared emission of $Tm^{3+}//Ho^{3+}$-doped antimony-silicate optical fiber has been presented. Luminescence at 2.1 μm corresponding to ⁵I₇ → ⁵I₈ transition in holmium was obtained by energy transfer between $Tm^{3+}$ and $Ho^{3+}$ ions. According to the Förster-Dexter theory, the efficiency of energy transfer of the $\text{}^3 F_4 (Tm^{3+}) \rightarrow \text{}^5 text{|}_7 (Ho^{3+})$ transition was calculated. The optimization of the activator content and the donor $(Tm^{3+})$/acceptor $(Ho^{3+})$ ions concentration ratio were conducted with the purpose of maximizing the efficiency of energy transfer. It made possible to select best-suited glass which was used to manufacture double-clad optical fiber. Strong and narrow bands of amplified spontaneous emission which formed as a result of energy transfer between thulium and holmium ions were observed in the fiber under exciting with radiation at 795 nm wavelength.

Opis:: In the paper the spectroscopic properties of antimony-germanate glass co-doped with $Yb^{3+}//Ho^{3+}$ has been investigated. Fabricated $Yb^{3+}//Tm^{3+}/Ho^{3+}$ co-doped glass is characterised by the emission of simultaneous multicolour upconversion luminescence. Strong blue $\text{}^{1}G_{4} \rightarrow \text{}^{3}H_{6}(Tm^{3+})$, green $\text{}^{5}F_{4} \rightarrow \text{}^{5}I_{8}(Ho^{3+})$ and red $\text{}^{5}F_{5} \rightarrow \text{}^{5}I_{8}(Ho^{3+})$ upconversion emission bands have been measured under 976 nm excitation at room temperature. Influence of molar ratio of active ions and excitation power on the colour coordinates (CIE-1931) have been investigated.
