Mn-doped silicate micro/nanowire bundles on silicon wafers: Synthesis and visible luminescence

The preparation of Zn₂SiO₄: Mn²⁺ nanowire bundles in a furnace with a horizontal quartz tube, was investigated. The single-crystalline micro/nanowires were directly grown on Si(100) substrates at a low temperature of 700°C. The observations from energy dispersive X-ray spectroscopy (EDS) indicate that both the head part and the end part of the nanowires have approximately the same atomic ratio. The results show that 1D micro/nanoscale materials have potential applications in fluorescent and electroluminescent devices coupled with silicon-based integrated technology.
