Abstract
In this study, we investigated the phase formation behavior of the FeSe₂-FeTe₂ system and the evolution of their thermoelectric transport properties. A series of Fe(Se_1-xTe_x)₂(x = 0, 0.2, 0.6, 0.8 and 1) compounds were synthesized by conventional solid-state reaction. Single phase orthorhombic structures were formed, except for FeSe_0.4Te_1.6(x = 0.2)...... More

Abstract
Development new high-performance thermoelectric materials for more efficient power generation systems and eco-friendly refrigerating systems has been challenging. Over the past few decades, thermoelectric studies have been focused on increasing the thermoelectric properties of materials. However, for conventional applications, developing of thermoelectric devices or modules with lower cost and..... 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
