Nd:BaF₂ nanoparticles have been prepared via co‐precipitation and a pumping filtration wash method. The phase composition and morphology of the synthesized nanoparticles were investigated by X‐Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FE‐SEM) analyses, respectively. SEM observations revealed the powder's particle size to be approximately 100‐200 nm after calcination at 600°C for 5 hours in Ar. The transparent Nd:BaF₂ ceramics were then fabricated by the one‐step vacuum sintering method at a temperature of 1200°C for 10 hours. SEM observations of the polished and thermally etched cross sections of the sintered ceramic revealed a highly homogenous microstructure with average grain size of 420 μm. Optical property characterization revealed that the transmittance of the ceramic reaches a maximum of ~70% in the infrared wavelength range, and an emission peak located at 1058 nm, excited by 808 nm light.

掺Nd的BaF2透明陶瓷的制备与性能

Nd：BaF ₂纳米粒子是通过共沉淀和抽滤洗涤法制备的。分别通过X射线衍射（XRD）和场发射扫描电子显微镜（FE-SEM）分析研究了合成纳米颗粒的相组成和形态。SEM观察表明，在Ar中于600°C煅烧5小时后，粉末的粒径约为100-200 nm。透明Nd：BaF ₂然后通过一步真空烧结法在1200°C的温度下烧结10个小时，制成陶瓷。烧结陶瓷的抛光和热蚀刻横截面的SEM观察显示出高度均匀的微观结构，平均晶粒尺寸为420μm。光学性质表征表明，陶瓷的透射率在红外波长范围内达到约70％的最大值，并且在808 nm的光激发下位于1058 nm处的发射峰。
