A pair of thallium salen derivatives was synthesized and characterized for potential use as monitors (or taggants) or as models for Group 13 complexes for subterranean fluid flows. These precursors were isolated from the reaction of thallium ethoxide

Monodisperse fluorescent organic/inorganic composite nanoparticles are synthesized through the spontaneous self-assembly of block copolymer polystyrene-block-poly(vinylpyridine) and rare-earth ions (europium, terbium, thulium, etc.). Depending on the

A novel technique is introduced for studying how rare earth ions are incorporated into the matrix of porous materials. Tb 3 + -doped silica sol-gel is annealed to form porous glass and immersed in an aqueous Gd(NO 3 ) 3 solution. Re-heating removes t

Analysis of glasses containing Eu and Tb dopants yields new insights about the role of Al 3+ co-doping in improving fluorescence yield of glasses containing rare earth (RE) dopants. Our work suggests that Al co-doping enhances fluorescence by two imp

Studies of terbium fluorescence intensity as a function of annealing temperature reveal the cause of increased fluorescence yields observed in rare earth doped sol-gel silicates prepared using N , N -dimethylformamide (DMF) as a drying control chemic

We have used trivalent terbium to investigate the mechanism behind fluorescence enhancement by Al 3+ co-doping. Our results indicate that rare-earth (RE) ions cluster together in aluminum-rich regions of the glass, and behave as if they were disperse

Spectroscopy of sol–gel silicate glasses containing Tb3+ is used to investigate the diffusion of water from the atmosphere into annealed glass samples. In materials that are annealed to 900 °C the blue–violet 5D3 → 7FJ fluorescence is comparab

In silicate sol–gel glass doped with trivalent terbium, the intensity of violet and blue fluorescence from the 5D3 level is highly dependent on terbium concentration, on the presence of Al3+ co-dopant, and on annealing conditions. Evidence is prese

BACKGROUND: Prestorage pooling of whole blood–derived platelets (PLTs) would simplify bacterial detection. This study evaluated the in vivo effect of the prestorage pooling of PLTs stored for up to 5 days, by assessing the corrected count increment
