Effect of flux on the spark-plasma-sintering (SPS) of translucent YVO<sub>4</sub>:Nd<sup>3+</sup> ceramics: microstructural evolution and optical properties
Enhanced optical properties of the (001) texture translucent YVO<sub>4</sub>:Nd<sup>3+</sup> ceramics can be achieved by adding LiVO<sub>3</sub> flux using a spark-plasma-sintering (SPS) technique. YVO<sub>4</sub>:Nd<sup>3+</sup> green body oriented along the (001) direction is successfully obtained from well-dispersed and highly stable YVO<sub>4</sub>:Nd<sup>3+</sup> suspension with suitable amount of LiVO<sub>3</sub> flux addition using 1wt% dispersant. The introduction of LiVO<sub>3</sub> flux can accelerate the sintering process and promote more effective densification during sintering. This ultimately leads to improved density of the YVO<sub>4</sub>:Nd<sup>3+</sup> ceramics compared to the sample without flux addition. The enhanced density, caused by the addition of the flux, finally results in the improved transmittance efficiency of the texture translucent YVO<sub>4</sub>:Nd<sup>3+</sup> ceramics.
