Dynamic mechanical and dielectric relaxations of poly(difluorobenzyl methacrylates)
(WILEY-BLACKWELL, 2000)
This work reports the mechanical and dielectric relaxation spectra of three difluorinated phenyl isomers of poly(benzyl methacrylate), specifically, poly(2,4-difluorobenzyl methacrylate), poly(2,5-difluorobenzyl methacrylate) ...
Integrating cross-correlation and relaxation algorithms for particle tracking velocimetry
(Springer, 2011)
An integrated cross-correlation/relaxation algorithm
for particle tracking velocimetry is presented. The
aim of this integration is to provide a flexible methodology
able to analyze images with different seeding and ...
Enhanced frequency upconversion in Er3+ doped fluoroindate glass due to energy transfer from Tm3+
(2002-12-01)
Energy transfer processes between Er3+ and Tm3+ were investigated examining the frequency upconversion emissions in a fluoroindate glass pumped at 790 nm. A 60-fold enhancement in the emission at ≈670 nm originating from ...
Estudio de los procesos de transferencia de energia entre iones Pr3+ dopados en Cs2NaYCl6
(Sociedad Chilena de Quimica, 1999)
Experimental studies are made for some selected electronic transitions in Cs2NaY1-xPrxCl6 crystals within the full doping range of the crystal lattice (0 ≤ × ≤ 1). Decay curves are recorded for various temperatures between ...
Upconversion luminescence in Er3+ doped Ga10Ge 25S65 glass and glass-ceramic excited in the near-infrared
(2013-02-28)
The infrared-to-visible frequency upconversion was investigated in Er 3+-doped Ga10Ge25S65 glass and in the transparent glass-ceramic obtained by heat-treatment of the glass above its glass-transition temperature. ...

Energy transfer upconversion on neodymium doped phosphate glasses investigated by Z-scan technique
(Elsevier BVAmsterdam, 2013-07)
Time-resolved Z-scan measurements were employed to characterize energy transfer upconversion on the phosphate glass matrix, named PAN (P2O5-Al2O3-Na2CO3), doped with increasing Nd3+ concentrations. It was observed a linear ...
