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。

关 键 词:荧光粉  发光性能  白光

Abstract: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.
Keywords:phosphors  optical properties  white light
