Sol-Gel Synthesis of Y_3Al_5O_(12):Ce~(3+), Tb~(3+) Rare Earth Phosphor

Y3Al5O12:Ce3+, Tb3+ rare earth phosphor was synthesized through sol-gel methods. The spectra scheme of X-ray diffraction indicates that the powder is with YAG crystal structure. The spectra schemes of excitation and emission indicate that the powder's maximal excitation peak is at 273nm, and the maximal emission peak is at 545nm. Color coordinate is: x=0.334, y=0.558. Excited by 273nm ultraviolet ray, the powder can emit bright green ray.
