Abstract

Energy transfer direction in <TEX>$Er^{3+}-Tm^{3+}$</TEX>-codoped fluorozirconate glasses has been studied. For <TEX>$Er^{3+}-Tm^{3+}$</TEX>-codoped glasses, the dependence of the green emission intensity on the pump power (Pex) of 800 nm has ranged from (Pex)<TEX>$^2$</TEX> to (Pex)<TEX>$^3$</TEX>. From this multistep absorption, a 1.48 <TEX>$\mu m$</TEX> emission from the <TEX>$^3F_4{\rightarrow}^3H_4$</TEX> transition on Tm<TEX>$^{3+}$</TEX> ion has been found to transfer into <TEX>$^4I_{13/2}$</TEX>, <TEX>$^4I_{9/2}$</TEX> and <TEX>$^4S_{3/2}$</TEX> on <TEX>$Er^{3+}$</TEX> ion. In case of the 1.06 <TEX>$\mu m$</TEX> pumping, the emissin ratio of <TEX>$^3H_4$</TEX> level in <TEX>$Tm^{3+}$</TEX> to <TEX>$^4I_{13/2}$</TEX> in <TEX>$Er^{3+}$</TEX> showed that the amount of the energy transfer from <TEX>$Tm^{3+}$</TEX> into <TEX>$Er^{3+}$</TEX> increased with the increasing concentration of <TEX>$Tm^{3+}$</TEX> ion. Our two kinds of pumping scheme suggest that the direction of dominant energy transfer between <TEX>$Er^{3+}$</TEX> and <TEX>$Tm^{3+}$</TEX> should be dependent on whether the <TEX>$^3F_4$</TEX> level resonates in <TEX>$Tm^{3+}$</TEX> the level or not.
