摘要：

InP nanorods and nanowires in the diameter range of 30-300 Angstrom and 100-1000 Angstrom in length were synthesized. For the preparation of nanorods, we used an organometallic precursor that decomposes thermally into InP and In metal particles. The [after serves as a nucleation catalyst for the growth of the semiconductor. Quantum rods of zinc blende structure with a high degree of crystallinity are grown along the (111) crystallographic planes. The absorption spectrum of InP nanorods with diameter of about 30 Angstrom and 100-300 Angstrom in length is in the visible spectral regime, suggesting a substantial blue shift with respect to the bulk (band gap 1.35 eV) that is due to size confinement. Moreover, the Stokes shift of the emission band in the quantum rods is substantially larger than the shift in the corresponding quantum dots.
