中文摘要：

采用高温固相法首次合成了由Eu3＋ 和Tb3＋ 共激活的Gd2MoB2O9 白色荧光粉,并对其发光性质进行研究.该荧光粉在近紫外光（375nm）激发下发出较强的白色荧光（常温）,光谱测试显示Gd2MoB2O9∶Eu3＋ ,Tb3＋ 的发射光谱中存在3个发射峰,分别位于486,543和613nm 处,能够合成较理想的白光;激发光谱在250～400nm 处均有较强的吸收,能与紫外LED很好地匹配,适用于白光LED.

英文摘要：

The Eu3＋and Tb3＋co-doped barium magnesium silicate Gd2 MoB2 O 9 phosphors,which can emit a full-colour light,were synthesized by high temperature solid state reaction,and their luminescence characteristics were investigated.The Gd2 MoB2 O 9∶Eu3＋,Tb3＋ emitted an intensive white light emission under excitation at 375 nm at room temperature.The spectra measurement show that the phosphors Gd2 MoB2 O 9∶Eu3＋,Tb3＋emit three colours light peaked at 486,543 and 613 nm,which were better suitable wavelength for composing white light.The excitation spectra having higher absorption between 250 and 400 nm,match with the UV-LED chips for white light emitting diode（w-LED）.
