Synthesis and Luminescence of BiPO4:Tb3+ Nanowires by a Hydrothermal Process

We synthesized BiPO4:Tb3+ nanowires by the hydrothermal process. The synthesized nanoparticles were measured using XRD, SEM, and luminescence spectrophotometry. The XRD patterns and SEM images indicate that reaction time induces phase changes but has no obvious influence on size and morphology. All samples show characteristic excitation and emission bands of Tb3+ ions. The BiPO4:Tb3+ samples reacted for 3.5h showed the highest emission intensity, which was induced by the pure monoclinic phase.
