摘要
玻璃具有透明、耐腐蚀等优点,是一种良好的基质材料。本文选用了TeO_2-ZnO、Bi_2O_3-ZnO-B_2O_3两种低熔点玻璃基体,掺杂(Sr_(0.1)Ca_(0.9))_(0.97)TiO_3∶Eu_(0.03)^(3+)荧光粉制备复合发光玻璃。研究表明,荧光粉在玻璃基体中的分散均匀性也受多种因素限制;荧光粉掺入玻璃基体中,受玻璃本身光散射的影响,发光性能受到了较大的限制。复合玻璃发光强度随着荧光粉掺杂量的增加而升高,但掺杂量超过一定值后,发光性能反而降低。掺杂量增加到一定程度时,得到的产物是烧结态陶瓷结构,其结构的变化降低了发光性能。对比TeO_2-ZnO、Bi_2O_3-ZnO-B_2O_3两种玻璃基体,TeO_2-ZnO玻璃与(Sr_(0.1)Ca_(0.9))_(0.97)TiO_3∶Eu_(0.03)^(3+)荧光粉有更好的匹配性。
Glass is a good substrate material due to its high transparent and durability.In this paper,TeO2-ZnO and Bi2O3-ZnO-B2O3 were chosen as glass matrix and （Sr0.1 Ca0.9）0.97TiO3 ∶ Eu0.033＋ phosphor was doped to prepare the composite luminous glass.The results show that the dispersive homogeneity of the phosphor powder is affected by many factors.And the luminescent properties of phosphor are affected by light scattering of the glass itself.With increasing of the phosphor,the luminescence intensity of the glass increased,but it decreased when the doped amount exceeds a certain value.The sample with an excess amount of phosphor is of a sintered ceramic structure which weakens its luminescence intensity.Comparing TeO2-ZnO with Bi2O3-ZnO-B2O3 glass substrates,the TeO2-ZnO glass matches better with the （Sr0.1Ca0.9）0.97TiO3 ∶ Eu0.033＋ phosphor.
