Analyzing the Erbium-Doped Yttrium Iron Garnet's Structure Using the Standard Ceramic Approach

Abstract

Polycrystalline Erbium Doped Yttrium Iron Garnet nanoparticles (ErxY3−XFe5O12) where x=0.6 were discussed in this article and their typical ceramic synthesis method. Looking at what others have found for x=0.1 and x=0.3 may show you the correlation between Erbium concentration and sample properties. Blending by grinding and calcination at 1100°C for one hour yields the stoichiometric combination (ErxY3→XFe5O12), where x=0.6. The sample is ground into pellets and then sintered for two hours at 1400°C to ensure its purity. To examine the sample's finer points, scientists employed scanning electron microscopy (SEM) and X-Ray Diffraction (XRD). With the greatest peak in the (420) plane, XRD was able to produce the required phase for the sample. All peaks are sharp and well-defined with the exception of a single little YFe2O3 peak that has been deformed due to the strong bonding between iron and yttrium. The (420) plane's structural characteristics were studied. The lattice constant and d-spacing are found to decrease as the erbium concentration rises. The fact that Yttrium and Erbium have almost identical ionic radii also explains the lack of variation in crystallite size. All three samples have large, almost identical grains as a result of the high sintering temperature.
