A novel metalorganic route for the direct and rapid synthesis of monodispersed quantum dots of indium phosphide

Abstract

Nanometric particles of InP are readily prepared by the decomposition of the complex In(PBu^t₂)₃ at 167 °C in 4-ethylpyridine; the resulting materials show marked quantum confinement effects, and was investigated using optical absorption and photoluminescence spectroscopies, and transmission electron microscopy.
