Identification of rare earth minerals associated to K-feldspar: Capacsaya project in Peru
(Springer NatureUK, 2022-01)
A recently discovered the rare-earth-rich site in Capacsaya, located at 123 km northwest of Cusco, at the south of Peru, contains signifcant quantities of light and heavy rare-earth elements such as neodymium, lanthanum, ...
Luminescent properties of hybrid materials prepared by the polymeric precursor method
(2013-07-22)
Rare earth complexes (RE) can be incorporated in silica matrixes, originating organic/inorganic hybrid materials with good thermal stability and high rare earth emission lines. In this work, the hybrid material was obtained ...
Frequency upconversion in rare-earth doped fluoroindate glasses
(2002-12-01)
We present recent results on frequency upconversion (UPC) obtained in fluoroindate glasses (FIG) doped with Ho3+, Tm3+ and Nd3+ ions and codoped with Pr3+/Nd3+ and Yb3+/Tb3+ ions. The results for the Ho3+-doped samples ...
Calorimetric investigations of luminescent films polycarbonate (PC) doped with europium complex [Eu(TTA)(3)(H(2)O)(2)]
(SPRINGER, 2009)
Polymers doped with rare earth complexes are advantaged in film production for many applications in the luminescent field. In this luminescent polycarbonate (PC) films doped with diaquatris(thenoyltrifluoroacetonate)europium(III) ...
Spent NiMH batteries-The role of selective precipitation in the recovery of valuable metals
(ELSEVIER SCIENCE BV, 2009)
The production of electronic equipment, such as computers and cell phones, and, consequently, batteries, has increased dramatically. One of the types of batteries whose production and consumption has increased in recent ...
Heavy metal oxide glass-ceramics containing luminescent gallium-garnets single crystals for photonic applications
(2021-05-25)
Glass-ceramics containing rare earth gallium garnets were obtained using glass compositions as reactional medium. This work reports on the synthesis, and structural, morphological, and optical characterizations of Er3+ and ...
Multifunctional EuYVO4 nanoparticles coated with mesoporous silica
(2016-11-01)
Mesoporous structures are interesting materials for the incorporation of dyes, drugs, and luminescent systems, leading to materials with important multifunctionalities. In a very unique way, these guest/host materials ...
Preparation and structural characterization of rare-earth doped lead lanthanum zirconate titanate ceramics
(ELSEVIER SCIENCE BV, 2009)
A new preparation route towards rare-earth (RE) doped polycrystalline lead lanthanum zirconate titanate (PLZT) ceramics (RE = Y(3+), Nd(3+), Yb(3+)), based on the use of doped lanthanum oxide or zirconia, is reported. ...
