摘要
在硼铝硅酸盐玻璃(43B_(2)O_(3)-25Al_(2)O_(3)-32SiO_(2))中进行Sm^(3+)/Ce^(3+)共掺杂,采用固相熔融法制备(B_(2)O_(3)-Al_(2)O_(3)-SiO_(2))-20Sm_(2)O_(3)-x CeO_(2)(x为0~6%,摩尔分数)玻璃,借助X射线衍射、扫描电镜、X射线光电子能谱、紫外-可见-近红外分光光度计等表征方法研究玻璃的结构和激光吸收性能。结果表明,所有样品均为玻璃状,Sm^(3+)和Ce^(3+)均匀分布。随CeO_(2)的摩尔分数从0增加到2%,玻璃中桥氧的摩尔分数从60.12%增加到63.82%,而当CeO_(2)的摩尔分数增加到6%时,桥氧的摩尔分数下降到59.41%。CeO_(2)摩尔分数为2%时玻璃的激光吸收性能最好,漫反射吸收峰位为1076 nm,漫反射率为48.10%。Sm^(3+)/Ce^(3+)共掺杂的硼铝硅酸盐玻璃是一种很有前景的1.06μm波长激光的吸收材料。
B_(2)O_(3)-Al_(2)O_(3)-SiO_(2)-Sm_(2)O_(3)-xCeO_(2)(x is 0−6%,molar fraction)glasses were prepared by solid-phase melting method with Sm^(3+)/Ce^(3+) co-doping in boron-aluminosilicate glasses(composition 43B_(2)O_(3)-25Al_(2)O_(3)-32SiO_(2)) with the help of X-ray diffraction(XRD),scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),UV-Vis-NIR spectrophotometer(UV-VIS-NIR)and other characterization methods to study the structure and laser absorption properties of the glasses.The results show that all samples are glassy with uniform distribution of Sm^(3+) and Ce^(3+).The percentage of bridging oxygen in the glasses increases from 60.12%to 63.82%with the CeO_(2) molar fraction increasing from 0 to 2%,and decreases to 59.41%when the CeO_(2) molar fraction increases to 6%.The laser absorption performance of the glasses is best at 2%CeO_(2) molar fraction,with the diffuse absorption peak at 1076 nm and the diffuse reflectance of 48.10%.The Sm^(3+)/Ce^(3+) co-doped boron-aluminosilicate glass is a promising material for laser absorption at 1.06μm wavelength.
