Optical Properties and White Emission from Dy³⁺ Doped in Y₂O₃-CaO-SiO₂-B₂O₃ Glasses

Abstract:

The Dy³⁺ doped Y₂O₃-CaO-SiO₂-B₂O₃ glasses with molar composition 25Y₂O₃ : 10CaO : 10SiO₂ : (55-x)B₂O₃, where x is 0.0 to 0.5 mol%, have been prepared by melt quenching method and are characterized through absorption, photoluminescence and decay analysis. From the luminescent spectra, observed a strong yellow and blue emission from ⁴F_9/2→ ⁶H_13/2 (575 nm) and ⁴F_9/2 → ⁶H_15/2 (482 nm) transition of Dy³⁺ ions respectively. The tunable white light emission at different excitation wavelengths are investigated through CIE 1931 diagram. The decay curves show the decreasing of lifetimes when addition of Dy₂O₃ concentration.
