主 题：methods absorption bonds
摘 要：GaP nanocrystals were synthesized by both the organic solvent reflux and high temperature high pressure benzene thermal synthesis *** effect of organic solvent on the optical absorption properties of GaP nanocrystals were *** results show that crystal grains of the sample synthesized by the latter method have better quality and *** solvents which consist of polar molecules and form strong chemical bonds with Ga atoms cause obvious redshift of the absorption spectra of GaP *** 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.
