摘要：
Mg2+ doped ZnSe nanoparticles are prepared by facile wet chemical route. N-methylaniline (NMA) is used as a surface passivating agent to obtain the agglomeration free nanoparticles. X-ray diffraction (XRD) pattern exhibits the cubic zinc blende structure of ZnSe. Ultraviolet visible spectroscopy (UV) shows the strong quantum confinement effect and the band gap is 3.56 eV. The emission spectrum confirms the incorporation of Mg2+ into the ZnSe. The presence of NMA is confirmed by Fourier transform infrared spectroscopy (FTIR). Transmission electron microscopy (TEM) result shows that the synthesized ZnSe is free from agglomeration and average size of the nanoparticles is about 15 nm. EDAX analysis confirms the presence of Mg2+ in ZnSe nanoparticles. (C) 2013 Elsevier B.V. All rights reserved.
