Effect of Eu3+ and Ce3+ codoping on the relaxation of Er3+ in silica‐hafnia and tellurite glasses
AbstractWe studied the spectroscopic properties of Er3+/Ce3+‐codoped tungsten‐tellurite glasses, obtained by melt‐quenching, and of Er3+/Eu3+‐codoped silica‐hafnia waveguides obtained by sol‐gel technique. The study of de‐excitation dynamics of the 4I11/2 and 4I13/2Er3+ states show that Ce3+ and Eu3+ codoping is effective in favoring the population feeding of the 4I13/2Er3+ level. Europium codoping also affects the 4I13/2Er3+ radiative efficiency. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
