Y型纳米碳管的结构表征与光学性能研究Investigation on Optical Property and Structure Characterization of Y-type Carbon Nanotubes
王晓敏,刘旭光
摘要(Abstract):
对Y型纳米碳管的形貌和超微观结构进行了SEM、HRTEM和XRD分析,并着重测试了其光学性能。结果表明,碳管内包裹Fe纳米微粒,管径分布在5 0~6 0nm之间;纳米碳管呈Y型是由于管内催化剂的粒度不均,使之在生长过程中产生分支;首次报道了产物的发光性能,认为其在红光范围内存在荧光效应。
关键词(KeyWords): Y型碳纳米管;HRTEM;荧光效应
