摘要
利用传统的高温固相法合成了2MgO·Al2O3·P2O5掺Eu,Tb3+,Mn2+系列荧光粉,并研究了它们的发光性能。荧光粉2MgO0.95·Al2O3·P2O5∶0.02Eu,0.02Tb,0.01Mn在近紫外光区具有很强的吸收。在近紫外光激发下,样品发射谱中包含明显的红光、绿光、蓝光3种发射。其CIE色度坐标(0.35,0.25)接近白光区域,在近紫外发光二极管方面有潜在的应用前景。
A series of samples 2MgO·Al2O3·P2O5 doped with Eu,Tb,Mn were prepared by the solid state reaction at high temperature.And their photo-luminescent properties were investigated.The phosphor 2MgO0.95·Al2O3·P2O5∶0.02Eu,0.02Tb,0.01Mn can exhibit intense red,green,and blue light emiss under near-UV light excitation.The luminescent properties were investigated and its CIE chromaticity coordinates（0.35,0.25） are close to white light region.The phosphor has potential application for near-UV emitting diodes.
