Abstract

Luminescence properties of heavily Yb-doped &lt;f&gt;Lu3Al5O12&lt;/f&gt; (Yb:LuAG) and &lt;f&gt;Lu3Ga5O12&lt;/f&gt; (Yb:LGG) single crystals grown by micro-pulling-down method were characterized. Charge transfer luminescence of &lt;f&gt;Yb3+&lt;/f&gt; was observed in both crystals. Photoluminescence spectra, temperature dependence of emission intensity and decay kinetics of these crystals were studied. Mean decay time of about &lt;f&gt;24 ns&lt;/f&gt; at &lt;f&gt;90 K&lt;/f&gt; (Yb5%:LuAG) and &lt;f&gt;21 ns&lt;/f&gt; at &lt;f&gt;110 K&lt;/f&gt; (Yb5%:LuGG) were observed. Strong thermal quenching at room temperature was measured for both Yb:LuAG and Yb:LGG. [Copyright &amp;y&amp; Elsevier]
