Tellurite based glass doped by Eu3+ ions - XPS measurements

Description

Eu³⁺ doped tellurite glass ceramics containing SrF₂ nanocrystals were prepared using melt quenching technique and subsequent heat treatment of glass in 370 °C for different time periods. Thermal properties of glass matrix have been determined based on DSC measurements. XRD and XPS results confirmed formation of SrF₂ nanocrystals in glass matrices after annealing at 370 °C. FTIR studies revealed absorption bands in the range of 500–850 cm⁻¹ characteristic to TeO₂ glasses. Obtained materials exhibited emission originated from the ⁵D_J (J = 0–2) to the ⁷F_J (J = 0–4) transitions of Eu³⁺ ions under 395 and 465 nm excitations. TRES measurements indicated presence of two different surroundings of the Eu³⁺ ions. In glass ceramics samples longer lifetimes of 615 nm emission of Eu³⁺ were achieved in comparison to the precursor glass.
