摘要：

In the paper the spectroscopic properties of antimony-germanate glass co-doped with Yb3+/Ho3+ has been investigated. Fabricated Yb3+/Tm3+/Ho3+ co-doped glass is characterised by the emission of simultaneous multicolour upconversion luminescence. Strong blue (1)G(4) -> H-3(6) (Tm3+), green F-5(4) -> I-5(8) (Ho3+) and red F-5(5) -> I-5(8) (Ho3+) upconversion emission bands have been measured under 976 urn excitation at room temperature. Influence of molar ratio of active ions and excitation power on the colour coordinates (CIE-1931) have been investigated.
