Abstract

Codoped Er³⁺ and Yb³⁺ nanocrystalline ZrO ₂-B₂O₃ phosphor obtained by a modified sol-gel method is demonstrated. The addition of up to 2.5 mol% B₂O ₃ to nanocrystalline ZrO₂:Yb(2%), Er(1%) keep the tetragonal rare-earth stabilized ZrO₂ phase; whereas higher B ₂O₃ content destabilize the tetragonal phase, leading to the tetragonal to monoclinic transition with no tetragonal ZrO₂ phase segregation. Visible upconversion of the luminescent active ions, Er ³⁺ and Yb³⁺, depend strongly on B₂O₃ content. The PL intensity is strongly quenched for high B₂O ₃ content due to increasing multiphonon relaxation processes related to BO and BOB vibronic modes.
