在发光粉废料处理中发现用高温固相反应和玻璃流股牵引方法,人工拉制了Eu3+掺杂ZnO-MgO-CdO-B2O3基质的光致发光玻璃纤维,直径为0.01～0.30 mm,长10余米.Eu3+离子613 nm的强发射归属于5D0-7F2电偶极跃迁,相对613 nm发射强度40%的591 nm发射归属于5D0-7F1磁偶极跃迁.说明Eu3+在局域环境中主要占据非对称中心格位.对不同浓度Eu3+的光衰曲线进行拟合,发现随着掺杂Eu3+浓度的增加,发光由单指数衰减变为双指数衰减.用SEM观察到玻璃纤维的表面光滑、低析晶、断口质密度高、断口贝纹呈明显沟状.并测试了发光玻璃纤维的一系列力学参数,也研究了Eu3+掺杂ZnO-MgO-La2O3-B2O3基玻璃纤维的光谱性能.
