Molybdate tungstate host foe upconversion
WebNaYTiO4:Yb3+, Er3+ phosphors with layered perovskite structure were prepared by a solid-state reaction method. The up-conversion luminescence (UCL) properties of the phosphors were studied under the 1550 and 980 nm excitations. The phosphors exhibited bright UCL. The observed emissions of the phosphors were similar and located at 510–580 nm and … Webtions of molybdate (or tungstate), with an ap-parentinhibitoryconstantof~5 mM.Bycontrast, the ATPase activity of AfModBC, which does not contain regulatory domains appended to the NBDs, was insensitive even to high concentra-tions of molybdate or tungstate (Table 1).
