Tuning into blue and red: europium single-doped nano-glass-ceramics for potential application in photosynthesis

Abstract

A series of SiO2–Al2O3–NaF–YF3 oxyfluoride glasses and β-YF3 nanocrystals embedded glass ceramics single-doped with europium ions were prepared by high-temperature melt-quenching to explore blue/red luminescent materials for potential application in the photosynthesis of green plants. Both Eu2+ and Eu3+ activators were demonstrated to coexist in this specially designed glass fabricated under ambient atmosphere, which can be well explained based on the optical basicity model of glass and evidenced by emission, excitation and time-resolved spectra. Furthermore, the crystallization strategy has been adopted to convert the precursor glasses into nano-glass-ceramics. As a result, Eu3+ ions partitioned into the precipitated orthorhombic YF3 nanophase, while Eu2+ ions remained in the glass matrix. Such spatial isolation of the different active ions in glass ceramics can effectively suppress adverse energy transfer between Eu2+ and Eu3+, leading to both intense Eu2+ blue and Eu3+ red emissions under ultraviolet light excitation.
