INDIUM PHOSPHIDE COLLOIDAL NANOCRYSTALS

摘要

A method of making a colloidal solution of indium phosphide semiconductor nanocrystals, includes forming a first solution by combining solvents and ligands; and heating the first solution to a temperature equal to or higher than 290°C and, while heating, adding to the first solution, a second solution containing trialkylindium, a phosphorus precursor and solvents and ligands so that a reaction takes place that forms a colloidal solution of indium phosphide semiconductor nanocrystals. The method further includes forming core shell indium phosphide semiconductor nanocrystals by forming semiconducting shells on the nanocrystals.
