Abstract
Because of their superior optical, and electrical properties, lead halide perovskites have emerged as potential materials for light-emitting-diodes. However, some obstacles have yet to be overcome for practical applications including low exciton binding energy, the difficulty of fabricating uniform perovskite films,, and their instability to heat, light, and moisture.

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
