摘要：
A sol-gel method has been developed to prepare lanthanide-codoped yttrium aluminium garnet (Y3Al5O12, YAG) ceramic samples. The XRD patterns of the polycrystalline Y3Al5O12:Nd,Ho and Y3Al5O12:Nd,Er powders sintered at 1000 degrees C showed the formation of monophasic garnet materials. A homogeneous distribution of rare-earth dopants in the YAG lattice was achieved in both cases. The morphological characterization of lanthanide-codoped YAG by scanning electron microscopy (SEM) showed the formation of highly agglomerated nanocrystalline samples. The luminescence properties of sol-gel derived doubly activated yttrium aluminium garnet samples were also investigated in the present study.
