纳米CdSe与聚4-乙烯基吡啶盐的复合与表征
摘要:
用巯基乙酸作稳定剂在水相中合成了CdSe纳米颗粒. 聚4-乙烯基吡啶季铵盐(PVPNI)通过静电作用与CdSe纳米颗粒复合形成了纳米复合材料.该复合材料通过红外光谱数据（IR）、电感耦合等离子发射光谱（ICP-AES）、透射电镜（TEM）等方法进行了表征,并通过紫外可见吸收光谱(UV-Vis)和荧光光谱(PL)对其光学性质进行了研究.结果表明,复合材料的形成,改善了纳米CdSe的分散性,并提高了纳米CdSe的荧光强度.

Synthesis and Characterization of CdSe/Poly (4-vinylpyridine) Quaternary Ammonium Nanocomposite
Abstract:
A stable CdSe nanoparticle hydrosol was prepared upon addition of mercaptoacetic acid as a stabilizer. A nanocomposite was formed based on electrostatic interactions by poly (4-vinylpyridine) quaternary ammonium with CdSe nanoparticle. The formation of nanocomposite was confirmed and characterized by infrared spectrum (IR), inductively coupled plasma atomic emission spectroscopy (ICP-AES), transmission electron microscopy (TEM),UV-Vis spectrophotomery (UV-Vis), photoluminescence (PL) spectrophotometry, etc.The dispersive property and luminescence intensity of CdSe nanocrystals were improved and increased by the formation of the composite.
