| 摘 要： | 采用高温固相烧结法制备了Er3+/Eu3+共掺杂和Yb3+/Er3+/Eu3+共掺杂系列硼硅酸盐玻璃样品。在978 nm半导体激光器抽运下,测量了样品的光致发光谱,分析了上转换机制。结果表明:随着Er3+浓度的增加,Eu3+的595 nm光谱强度增强;Eu3+的692 nm光谱强度随Yb3+浓度增加而增强,并明显强于595 nm光谱。Er3+/Eu3+、Yb3+/Eu3+之间的能量传递和合作上转换等机制导致Eu3+离子上转换发射。

| Abstract: | A series of Er3+ /Eu3+ co-doped, Yb3+ /Er3+ /Eu3+ co-doped borosilicate glasses have been prepared by high-temperature solid-phase melting. Under 978 nm semiconductor laser excitation, the up-conversion emission spectra of the samples were measured, and up-conversion mechanism was analyzed. The emission intensities of Eu3+ ions at 595 nm and 692 nm were enhanced with increasing concentration of Er3+ , Yb3+ , respectively. And emission intensity at 692 nm is stronger than that at 595 nm. The cooperation up-conversion and the energy transfer between Yb3+ and Eu3+, Er3+ and Eu3+ lead to a strong up-conversion emission of trivalent europium ions. |
