Investigation of Structural Morphology,Optical and Electrical Property Optimization of Rare Earth Doped Yttrium Oxide Prepared Through Swirling Spray Flame Synthesis
Yttrium-based nanoparticles doped with rare earth have promising applications in the fields of fluorescent material,laser crystals and transparent ceramics.In this paper,a one-step continuous synthesis of Re:Y2O3(Re=Ce,Nd,Yb,La)nanoparticles was prepared by swirling spray flame synthesis method,and the structural morphology,optical and electrical properties of the synthesized nanoparticles were investigated.The results show that the synthesized nanoparticles have uniform particle size distribution(about 10 nm),good crystallinity and cubic phase.The distortion of lattice cell is positively correlated with the ionic radius of the doped elements.Different rare earth doping elements all lead to higher relative permittivity and dielectric loss.In the wavelength range of 200～2000 nm,1％Yb doping brings the highest increase in spectrum absorption,which is 22.83％.5％La doping brings the lowest increase in spectrum absorption,which is 14.92％.In addition,the 5％La doping decreases the forbidden band width to 4.53 eV,resulting in a significant increase in spectrum absorption in the UV region.
