摘要： 采用溶胶－凝胶法在低温下合成了 Ｙ３Ａｌ５Ｏ１２：０．０８Ｃｅ３＋； ０．１２Ｔｂ３＋稀土荧光粉．通过 Ｘ射线衍射（ＸＲＤ）分析及激发、发射光谱测试结果表明：合成的粉末为ＹＡＧ晶体结构，粉体 的最大激发峰为２７３ｎｍ，最大发射峰为５４５ｎｍ，色坐标为：ｘ＝０．３３１；ｙ＝０．５５８，在２７３ｎｍ的紫 外光激发下发出明亮的绿光．

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.
