Process for producing a suspension of GaP nanoparticles

摘要

The invention relates to the technology for production of GaP nanoparticles in the form of powder or colloidal suspensions, in particular to processes for producing nano-sized GaP particles.The process for producing a suspension of GaP nanoparticles includes the dissolution of sodium phosphide in toluene, separate dissolution of gallium acetylacetonate in toluene for 2 hours at the temperature of 90…100°C, mixing of solutions by ultrasonic vibrations within 4 hours, then addition in the produced solution of trioctylphosphine oxide. After 12 hours the suspension of nanoparticles is separated from the sediment. The atomic ratio of Ga:P is 1:(1.8…3.0).
