Abstract :

Controlled synthesis of nanoparticles of InP/ZnS type with core/shell structure is reported using the colloid chemistry method called "one-step injection precursors without hot" at different temperatures. Varying the conditions of reaction temperature (100-320�°C), it was possible to control the formation of the shell and average particle sizes (2-10 nm). Color changes were clearly observed in the colloidal dispersions according to the reaction temperature. The obtained semiconductor nanoparticles presented crystalline structure core/shell, uniformity in size and exhibit a dependence of emission in the range of 450-650 nm. The formation, size, structure, composition and optical properties of the samples were characterized using techniques transmittance, HRTEM, XRD, EDS. UV-Vis spectroscopy and room-temperature photoluminescence.
