Abstract GaP nanocrystals were synthesized by both the organic solvent reflux and high temperature high pressure benzene thermal synthesis methods. The effect of organic solvent on the optical absorption properties of GaP nanocrystals were studied. The results show that crystal grains of the sample synthesized by the latter method have better quality and uniformity. The solvents which consist of polar molecules and form strong chemical bonds with Ga atoms cause obvious redshift of the absorption spectra of GaP nanocrystals. The absorption spectra redshift much more if the solvent molecules have π electrons which involved in the formation of complex bond between Ga atoms and solvent molecules.
