用均相沉淀法在水溶液中合成了锖掺杂的笨甲酸镧发光物质,确定了它们的组成,研究了它们的发光强度与合成酸度和Dy~(3+)离子含量之间的关系。
The luminescent materials of lanthanum phosphors were synthesized by homogeneous precipitation in aqueous solution. The composition of lanthanum phosphors was determined. The relationship between their luminescence intensity and the content of Dy 3+ ions was studied.
