Synthesis and spectral properties of lutetium-doped CeF3 nanoparticles

CeF3 and lutetium-doped CeF3 nanoparticles with the dopant concentration of 17, 25, 30, 42 and 50 mol% (molar ratio, Lu/Ce) were synthesized. XRD patterns were indexed to a pure CeF3 hexagonal phase even under the dopant concentration of 50 mol%. Environmental scanning electron microscopy-field emission gun (ESEM-FEG) was used to characterize the morphology of the final products. From the luminescence spectra of the products, we can get a broad emission ranging from 290 to 400 nm with peak at 325 nm. Lutetium-doping increases the luminescence intensity. We got. the most intense luminescence at the dopant concentration of 30 mol%.

Bill - No. 177 1892

The Act confirming agreement between the Canadian Niagara Power Company and the Queen Victoria Niagara Falls Park Commission. 2nd Session, 7th Legislature, 55 Vict., 1892.

HG 177.35-177.45

Dark brown sediment with organic matter. There are two main domains; a coarse grained domain, and a finer grained domain. The coarse grained domain contains grains ranging from small to medium in size, and angular to sub-rounded in shape. In the coarse grained domain, grain crushing/stacking is common, with a few lineations and rotation structures. In the finer grained domain, grains are small and range from sub-angular to sub-rounded in shape. Lineations are abundant in this domain.
