Structural and spectral properties of LaLu0.7Er0.3O3 polycrystalline

Abstract

Abstract: LaLu0.7Er0.3O3 polycrystalline was synthesized by the co-precipitation method. It’s structure were determined by Retvield refinement to X-ray powder diffraction, and the scale of powder particles was also estimated. The optical spectroscopy of the LaLu0.7Er0.3O3 polycrystalline was studied by absorption and emission measurements at room temperature. Under the excitation of 380 nm light, The 1.5 μm decay curve of Er3+ (4I13/2→4I15/2) was also studied. The experimental results present that，LaLu1-xErxO3 is a potential infrared laser material, which has further research value.

Key words: materials, LaLu1-xErxO3, nano-crystal, co-precipitation method, structure, photoluminescence
