Abstract

RE/Yb (RE = Ho, Tm and Er) co-doped [30-(30/88)×(x + y)]La₂O₃-[58-(58/88)×(x + y)]Al₂O₃-4ZrO₂-8TiO₂ (LAZT:RE/Yb, RE = Ho, Tm and Er) glasses were fabricated by a containerless aerodynamic levitation method, which overcomes the difficulty of preparing heavy metal oxide glass by the melting-quenching method. All LAZT:RE/Yb glasses present amorphous state, and have high transmittance and excellent mechanical properties, exhibiting certain practical engineering application value. All LAZT:RE/Yb glasses exhibit excellent fluorescence luminescence performance stimulated by the RE/Yb co-doping, in which the upconversion emission colors are orange for LAZT:0.5Ho/0.9Yb glass and LAZT:xEr³⁺/yYb³⁺ glasses, and blue purple for LAZT:0.8Tm/7Yb glass, providing possibility of adjusting laser color. The upconversion emission processes of LAZT:0.5Ho/0.9Yb glass and LAZT:2Er³⁺/12Yb³⁺ glasses involve upconverted two-photons process, while the upconversion emission process of LAZT:0.8Tm/7Yb glass involves upconverted three-photons process.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
