摘要

利用溶胶-凝胶法在加入H

助熔剂的环境下制备了掺杂不同量Mn

的Zn

SiO

绿色发光粉。用X射线衍射仪和荧光光谱仪对其结构和光致发光性能进行了测试分析。结果表明:900 ℃还原气氛下退火后

样品呈现明显的绿色

最佳掺杂摩尔分数为2%

当掺杂量超过2%后光谱发生强烈的浓度猝灭效应。最后

对这种物质的发光机理进行了分析。

Abstract

Different content of Mn

doped Zn

SiO

green phosphors were prepared by sol-gel method under the dopants of boron ions.The photoluminescent properties and structure of the samples were studied by fluorescence spectroscopy and X-ray diffraction

respectively. Results showed that

after annealed at 900 ℃ in reducing atmosphere

the sample exhibits a clear green color and the best doping mol fraction is 2%. A strong concentration quenching effect is presented when the concentration of

＞2%

the possible luminescence mechanism of the samples was also analyzed in this paper.
