Transparent and colorless CeO2-activated borogermanate glasses, with the nominal composition of 25B2O3–40GeO2–14Gd2O3–1CeO2–20MO (M=Ba, Sr, Ca and Mg), were synthesized by a melt-quenching method in air. Their optical properties including the transmittance, photoluminescence (excitation and emission spectra), the luminescence decay curves, as well as the temperature-dependent emission spectra were...
The BaGd1.8−xYxEu0.2O4 (0⩽x⩽1.8) phosphors were synthesized by the conventional high temperature solid-state reaction (SSR) method at 1300°C in air. The structure and optical performances of the as-synthesized phosphors were characterized using X-ray powder diffraction (XRD), excitation and emission spectra, X-ray excited luminescence (XEL) and thermoluminescence (TL) spectra. The XRD results reveal...
