(Gd,La)2-x O2CO3:Eux3+(0.01 ≤x≤0.04) were synthesized via a flux method at 400°C, and their photoluminescence properties under vacuum ultraviolet (VUV) excitation were examined. The excitation spectra showed two bands in the region from 125 nm to 300 nm, the first band centered at 190 nm was ascribed to absorption of related CO32- complex, and the second broad band centered at 246nm and 278nm in Gd2O2CO3:Eu3+ was ascribed to the charge transfer band of O2-→ Eu3+. Series samples exhibited red emission at around 611 nm under vacuum ultraviolet excitation corresponding to the 5D0→ 7F2.transition of Eu3+.

Sr2CeO4: Ho3+ was prepared by high-temperature solid-state method. The products were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and photo luminescent (PL). The Sr2CeO4:Ho3+ phosphors showed a red emission under the near-ultraviolet excitation (280 nm) and the main emission centered at 475 nm. It has been found that A+ (A+ = Li+, Na+ or K+) codoped Sr2CeO4: Ho3+ phosphors could lead to a remarkable increase of photoluminescence. Luminous intensity was the highest when doping Li+ ions. Investigation indicated that Sr2Ce0.989O4: 0.001Ho3+, 0.01Li+ exhibited the strongest emission. The average particle size was about 6 um. The optimum sintering temperature was 1200 °C and the possible mechanism was also discussed.
