الوصف: | In the Y2O3-Al2O3 system, compounds Y3Al5O12 (yttrium aluminum garnet, YAG), YAlO3 (yttrium aluminum perovskite, YAP), and Y4Al2O9 (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 Ce3+ activation were also prepared and exhibited characteristic photoluminescence. |
