Abstract

AbstractPreparation 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.
