Zn1-xMnxSe (x = 0-0.15) nanobelts and nanotubes can be synthesized via the removal of diethylenetriamine (DETA) in l-octadecene (ODE) and ethylene glycol (EG), respectively, using [Zn1-xMnxSe](DETA)(0.5) nanobelts as a template. The as-prepared ZnSe nanobelts are single-crystalline and grown along the [001] direction, and the ZnSe nanotubes consist of nanoparticles assembled along the [001] direction. In addition, Mn2+-doped Zn1-xMnxSe (x = 0.05, 0.10, 0.15) nanotubes are prepared for the first time if doped [Zn1-xMnxSe](DETA)(0.5) nanobelts are used as the template. The formation process of Zn1-xMnxSe nanobelts and nanotubes has been studied, and a plausible mechanism is proposed. Photoluminescence (PL) and electron paramagnetic resonance (EPR) spectra of Zn1-xMnxSe nanobelts and Zn1-xMnxSe nanotubes have been investigated.
