| Abstract: A series of aluminates were successfully synthesized via hydrothermal precipitated method, followed by sol-id-state reaction at high temperature. The optimum condition to synthesize Sr3Al2O6 was determined by adjusting the pH value of the solutions. The as-prepared Sr3Al2O6 with lattice constant a=1.58556nm were characterized by X-ray diffraction (XRD) and photoluminescence spectroscopy (PLS). In PL spectrum, a strongest peak at 655nm is observed, which is corresponding to red light, with an excitation wavelength of 459nm. |
