초록
Elongated CdSe nanoparticles with a diameter of 3-7 nm have been successfully synthesized usingtwo surfactants of trioctylphospine (TOP) and hexadecylamine (HDA) at 160oC. The formation of elongated CdSenanoparticles is possibly due to the cooperative effects from both the diferent binding capability of two sur-factants (TOP and HDA) and intrinsically anisotropic crystal structure of the CdSe. The electron diffraction pat-tern of CdSe nanoparticles revealed the formation of wrzite phase. The CdSe samples showed red-shiftedparticles. The relatively broad absorption band can be attributed to the surface state of CdSe nanoparticles. Thepossible formation mechanism of elongated CdSe nanoparticles was proposed and the characteristics of CdSehave been discussed as well.
