Abstract

The invention relates to a method for preparing yttrium lanthanum oxide transparent ceramic which can improve 3-micron light-emitting performance of Er<3+> and is doped with Nd and Er and belongs to the technical field of special ceramic manufacturing processes.According to the method, high-purity Y2O3 serves as the raw material, La2O3 serves as the sintering aid, Er2O3 serves as the active ion, Nd2O3 serves as the sensitize ion, a traditional ceramic preparation process is adopted, at a low temperature, a proper sintering system is utilized, and the (NdxEr0.01Y0.89-xLa0.1)2O3 transparent ceramic is prepared through a solid phase sintering method by means of a proper sintering system.It is verified by detection experiments that the low-concentration Nd<3+> serves as the sensitizing ion, so that light emitting intensity of the 3-micron waveband of the Er<3+> in the yttrium lanthanum oxide transparent ceramic can be remarkably improved while light emitting of the 1.5-micron waveband of the Er<3+> can be effectively inhibited; according to the method, by means of the co-doped low-concentration sensitizing ion Nd<3+>, the light emitting intensity of the 3-micron waveband of the Er<3+> in the yttrium lanthanum oxide transparent ceramic can be remarkably improved, and possibility of efficient laser operation of the 3-micron waveband of the Er<3+> in the yttrium lanthanum oxide transparent ceramic is provided.

Description

technical field [0001] The invention relates to a preparation method of lanthanum yttrium oxide transparent ceramics doped with Nd and Er, and belongs to the technical field of special ceramic manufacturing technology. Background technique [0002] As we all know, Er 3+ The laser output in the 1.5μm band has many excellent properties, including eye safety and a good atmospheric transmission window. However, in recent years it has been found that Er 3+ The 3μm mid-infrared laser also has excellent performance, and it has potential applications in many aspects such as laser surgery, toxic gas monitoring, infrared countermeasures and free space communication. However, due to Er 3+ The lifetime of the upper energy level of the 3μm laser is shorter than the lifetime of the lower energy level, and it is difficult to form the necessary condition for laser operation - the inversion of the number of particles - resulting in the so-called "self-termination effect", and the formatio...
