摘要：

In the Y 2O 3-Al 2O 3 system, compounds Y 3Al 5O 12 (yttrium aluminum garnet, YAG), YAlO 3 (yttrium aluminum perovskite, YAP), and Y 4Al 2O 9 (yttrium aluminate monoclinic, YAM) are well known. YAG and YAP are of considerable technological importance. Conventional solid-state reaction techniques require high sintering temperatures (above 1800°C) to prepare phase-pure compounds. Though several soft chemical routes have been explored for synthesis of YAG, YAP and YAM, most of these methods are complex. Moreover, phase-pure materials are not obtained in one step and prolonged annealing at temperatures around 1000°C is necessary. In this paper, one-step combustion synthesis of these compounds is reported using a modified procedure and employing mixed (glycine + urea) fuel. Phosphors based on Ce 3+ activation were also prepared and exhibited characteristic photoluminescence. © Allerton Press, Inc., 2012.
