Abstract: InP colloidal quantum dots(QDs) are prepared using the dehalosilylation reaction of InCl3·4H2O and P(Si(CH3)3)3 in trioctylphosphine oxide (TOPO).The TOPO is used as capping groups and colloidal stabilizer,and the dodecylamine added during the later period of the reaction period is used as surfactant.Particle size,crystallinity,lattice structure,morphology,and size distributions are measured using powder X-ray diffraction and transmission electron microscopy.The optical properties are characterized with photoluminescence and ultraviolet spectrometers.These results indicate that the average diameter of the QDs,which possess good crystallinity and size distribution,is 2.5nm,and hence they clearly exhibit quantum confinement effect.
