Solvothermal Synthesis of CdSe Nanowires Assisted with Polyacrylamide

doi:10.3724/SP.J.1077.2007.00838

Abstract

Abstract: CdSe nanowires with an average diameter of 20nm and lengths of several hundreds of nanometers to several micrometers were synthesized by a solvothermal method assisted with polyacrylamide (PAM) at 180℃. The structure and morphology of as prepared products were characterized by XRD, TEM and HRTEM. Also, the effect of reaction time on nanowire growth and the growth mechanism were discussed. The optical properties of CdSe nanowieres were investigated by UV-vis and fluorescence spectroscopy measurements. An absorption peak found at 660nm in the UV-vis spectrum indicates that the as-prepared CdSe nanowires show a strong blue shift due to quantum confinement effect.

Key words: CdSe, nanowires, solvothermal, polyacrylamid
