| Abstract: | 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, .=0.558. Excited by 273nm ultraviolet ray, the powder can emit bright green ray. |
