Nd:BaF 2 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:BaF 2 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.
