摘要：

Preparation conditions and phase composition of polycrystalline SnO2:Eu luminophores are investigated. The results show that the luminescence intensity of SnO2:Eu obtained from Sn(II)-containing precursors, (hydroxide or oxide), is considerably higher than that from Sn(IV) oxide hydrate. It is considered that the creation of luminescence centers in SnO2:Eu is connected to the formation of intermediate Sn(II)-Sn(IV) oxides during the oxidation.
