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 $^{1}G_{4} → ^{3}H_{6}(Tm^{3+})$, green $^{5}F_{4} → ^{5}I_{8}(Ho^{3+})$ and red $^{5}F_{5} → ^{5}I_{8}(Ho^{3+})$ 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.
