Resumo IPEN-doc 14119 Absorption spectroscopy potentially identifies carcinoma on fine-needle aspiration biopsy of thyroid nodules2006 - PARISE, O.; ZEZELL, D.M.; ALBERO, F.G.; VIEIRA JUNIOR, N.D.; KUHBAUCHE, R.; TAKENAKA, M.; TARELHO, L.V.G.Artigo IPEN-doc 10245 Dynamics of Tm-Ho energy transfer and deactivation of the sup(3)Fsub(4) low level of thulium in fluorozirconate glasses2004 - VILA, L.D.; GOMES, L.; TARELHO, L.V.G.; RIBEIRO, S.J.L.; MESSADDEQ, Y.Artigo IPEN-doc 09790 Mechanism of the Yb-Er energy transfer in fluorozirconate glass2003 - VILA, L.D.; GOMES, L.; TARELHO, L.V.G.; RIBEIRO, S.J.L.; MESSADDEQ, Y.Artigo IPEN-doc 08647 Deactivation effects of the lowest excited states of Ersup(3+) and Hosup(3+) introduced by Ndsup(3+) ions in LiYFsub(4) crystals2002 - JAGOSICH, F.H.; GOMES, L.; TARELHO, L.V.G.; COURROL, L.C.; RANIERI, I.M.Artigo IPEN-doc 10244 Investigation of the multiphoton excitation process of the 4fsup(2)5d configuration in LiYFsub(4) and LiLuFsub(4) crystals doped with trivalent neodymium ion2004 - LIBRANTZ, A.F.H.; GOMES, L.; TARELHO, L.V.G.; RANIERI, I.M.Artigo IPEN-doc 11159 Enhancement of blue upconversion mechanism in YLiFsub(4):Yb:Tm:Nd crystals2005 - COURROL, L.C.; RANIERI, I.M.; TARELHO, L.V.G.; BALDOCHI, S.L.; GOMES, L.; VIEIRA JUNIOR, N.D.Artigo IPEN-doc 11161 Enhancement of europium luminescence in tetracycline-europium complexes in the presence of urea hydrogen peroxide2005 - SILVA, F.R.; COURROL, L.C.; TARELHO, L.V.G.; GOMES, L.; VIEIRA JUNIOR, N.D.An increase in the europium emission band was observed, for the first time, with addition of urea hydrogen peroxide to the tetracycline–europium (Tc–Eu)solution. We have observed that the wavelength, the band width and the area of 5D0 →7F2 europium transition change with the urea hydrogen peroxide concentration. We claim that the tetracycline–europium complexes can be used as probes of urea hydrogen peroxide concentration.Artigo IPEN-doc 11667 Urea hydrogen peroxide determination in whole blood using europium tetracycline probe2006 - COURROL, LILIA C.; MARUMO, MARIA H.B.; TARELHO, LUIZ V.G.; SILVA, FLAVIA R.O.; MANSANO, RONALDO D.; GOMES, LAERCIO; VIEIRA JUNIOR, NILSON D.; SCHOR, NESTORWe introduce the use of a lanthanide complex, tetracycline–europium, for the clinical diagnosis of urea hydrogen peroxide in human whole blood. The values obtained agree with the urea concentration variation verified in 49 patients, including 12 predialysis, 12 peritoneal, and 15 dialysis subjects, and 10 controls. This method is noninvasive and can help in the identification of renal and cardiac diseases.Artigo IPEN-doc 12253 Study of optical properties YLF:Nd:Tm crystals2007 - COURROL, LILIA C.; RANIERI, IZILDA M.; TARELHO, LUIZ V.G.; BALDOCHI, SONIA L.; GOMES, LAERCIO; VIEIRA JUNIOR, NILSON D.
