摘要： Compositions and methods for determining the origin location of a subterranean rock sample. Compositions include a nanoparticle tag with a fluorescent core and a polymer shell. The fluorescent core can include up-converting nanoparticles, rare earth element doped oxide, long persistent fluorescent materials, or encapsulated lanthanide complexes. Methods include mixing a nanoparticle tag into a fluid, flowing the fluid through a work string into a subterranean formation, recovering subterranean rock samples from the subterranean formation, and determining an origin location of the subterranean rock sample by detecting the presence of the nanoparticle tag on the sample.

摘要： The present invention relates to methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is narrower which renders a subsequent size-selected separation process superfluous.

摘要： A fluorescent material includes first and second phosphors. The first phosphor is a light-storing phosphor, which is represented by the general formula (M1-a-bEuaQb)Al2O4, wherein M is one type selected from the group consisting of Mg, Ca, Ba, Sr and Zn; Q is one type selected from the group consisting of Pr, Nd, Dy, Er and Ho; a is a number that satisfies 0.0001≦a≦0.5; and b is a number that satisfies 0.010≦b≦0.5. When the fluorescent material is excited for about 15 minutes by ultraviolet irradiation having about 365.0 nm wavelength with an intensity of 0.5 mW/cm2, and the color of the afterglow of the fluorescent material is measured 1 minute and 10 minutes after excitation is terminated, an amount of change between chromaticity measured 1 minute after excitation and that measured 10 minutes is in the range of −0.001≦x≦0.009 and −0.009≦y≦0.006.
