稀土蓝绿色荧光粉的研制

Preparation of Rare Earth Blue-green Phosphor

用某种碱土金属离子部分置换铝酸锶中的Sr2+,合成了发光峰值为487nm的蓝绿色荧光体Sr4-x1-x2AlxO25(M=Ca,Mg,Ba)。为提高发光体的亮度,考察了助熔剂对荧光体发光亮度的影响。

Effect of some alkali earth ions substituting in part for Sr^(2+) in strontium aluminate was investigated.A blue-green emitting phosphor Sr_(4-x_1-x_2)M_(x_1)Eu_(x_2)Al_xO_(25) with emission peak at 487nm was synthesized.In order to increase the luminescence of the phosphor,the influence of flux was examined.
