STUDY ON THE FACTORS AFFECTING THE PARTICLES SIZE OF GAP NANOCRYSTALLINE MATERIALS

Nanometer GaP was synthesized by reacting GaCl3-Et2O and GaCl3-benzene with Na3P, respectively, under high-temperature, high-pressure benzen e-thermal conditions. The results indicated that the products prepared by reacting GaCl3-Et2O with Na3P has a smaller and nearly monodispers ed crystal size, but the yield is poor, while the product of reaction between GaCl3-benzene and Na3P has much wider crystal size distributio n and rather high yield. In addition, the process of the formation and growth of GaP nanocrystals was studied. (C) 1998 Elsevier Science B.V . All rights reserved.
