Luminescent properties and stability of Eu²⁺ ions in SrBPO₅ and SrAl₂B₂O₇
Using the luminescence spectroscopy, the stability of Eu²⁺ ions in SrBPO₅ has been shown to exceed significantly that in SrAl₂B₂O₇. The luminescence spectrum of Eu²⁺ in SrBPO₅ and SrAl₂B₂O₇ consists of a broad band with a maximum at 390 and 490 nm, respectively. In contrast to SrBPO₅, the stabilizat...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Using the luminescence spectroscopy, the stability of Eu²⁺ ions in SrBPO₅ has been shown to exceed significantly that in SrAl₂B₂O₇. The luminescence spectrum of Eu²⁺ in SrBPO₅ and SrAl₂B₂O₇ consists of a broad band with a maximum at 390 and 490 nm, respectively. In contrast to SrBPO₅, the stabilization of Eu²⁺ ions in SrAl₂B₂O₇ requires an annealing in reducing medium. It is supposed that this is caused by the difference in the effectiveness of the excess charge compensating processes for Eu³⁺ which can be quantified by the formal volume per oxygen atom (V₀) in the compound structure. |
