Influence of reaction time on the particle size of GaP nanocrystals

GaP nanocrystals was synthesized by high temperature high pressure benzene thermal synthesis method, the effect of reaction time on the particle size and its distribution was investigated by means of TEM and optical absorptio n spectrum measurement. The results indicated that as the time prolonged,a blue - shift became obvious in the optical absorption spectra of the GaP be nzene solution. The cause for this phenomenon was investigated in this pape r and the experimental results supported our conclusion.
