Preparation and Luminescent Properties of Sr_3P_(2-x)V_xO_8:Eu(0≤x≤2.0)

研究了B位掺杂的Sr3P2-xVxO8(0≤x≤2.0)基质和Eu3+掺杂Sr3-3yEu2yP1.2V0.8O8(0<y≤0.30)系列样品在紫外光激发下的发光性质。以两种不同紫外激发波长激发Sr3P2-xVxO8基质时,局部最大发光强度似乎与x值间存在周期性变化,且x=0.6和0.8时,Sr3P2-xVxO8样品具有最大发光强度。在Sr3P1.2V0.8O8基质中,Eu3+掺杂的最佳浓度为y=0.20。

The luminescent properties of B-site doped Sr3P2-xVxO8（0≤x≤2.0） matrix and the series Eu3＋ doped Sr3-3yEu2yP1.2V0.8O8（0y≤0.30） samples were investigated under UV light excitation.Sr3P2-xVxO8（0≤x≤2.0） matrix can be excited by UV light with different two UV activation wavelengths.The locality maximum light intensity seemly existed periodic variation with value of x,when values of x were respectively 0.6 and 0.8,the Sr3P2-xVxO8 samples had the maximum light intensity.The optimal concentration of doping Eu3＋ was y value of 0.20 in Sr3-3yEu2yP1.2V0.8O8 matrix.
