Abstract
Perovskite manganese La_0.7Sr_0.3MnO₃ (LSMO) powders were prepared by sol-gel synthesis and calcination in the temperature (T ) range of 500~1200 o C and their structures and electromagnetic (EM) wave absorption properties were investigated. X-ray diffraction (XRD) analysis revealed that the crystalline perovskite phase can be formed at T ≥ 600 ^oC...... More

Abstract
Multi-layer core-shell nanoparticles (YVO₄:Nd³⁺/mSiO₂/SiO₂) consisting of silica cores (SiO₂), mesoporous silica (mSiO₂) intermediate layers, and Neodymium doped rare-earth phosphor (YVO₄:Nd³⁺) shell layers were successfully synthesized using the stepwise sol-gel method. The morphological structure and optical properties of the functional core-shell nanoparticles were characterized and evaluated by transmission electron microscopy (TEM),..... More
