| 摘 要： | 采用高温固相法合成了Eu2+激活的Ba5-zSrx(PO4)3cl(x=0,1,2,3,4,5)蓝色发光粉.样品的XRD衍射光谱表明,随着Ba2+浓度的增加,衍射峰向小角度方向移动.所有样品的激发光谱都存在两个激发峰,随着Ba2+浓度的增加,两个尖峰逐渐靠近,同时激发峰强度降低,这种现象可以通过位形坐标解释.激发和发射...

| Abstract: | Eu~(2+)doped Ba_(5-x)Sr_x(PO_4)_3Cl(x=0,1,2,3,4,5)blue phosphors particle were prepared by the conventional solid-state reaction method.It can be clearly exhibited that XRD peaks of the samples shift to the smaller angle side with the increasing content of Ba~(2+).In excitation spectra,two peaks fell toward each other of all the samples and their intensities decreased with increasing content of Ba~(2+),which can be explained by the configuration-coordinate model.Seen from the emission spectra,the position o... |
