论文摘要
Eu3+ ions doped Zn（OH）F and ZnO micro-structures with specific morphologies were synthesized by a simple hydrothermal method only through altering the addition amount of NH4F and hexamethylenetetramine（HMT）. The phase structure, morphology and luminescence properties of the as-prepared samples were characterized by X-ray powder diffraction（XRD）, scanning electron microscopy（SEM）,transmission electron microscopy（TEM）, photoluminescence（PL） spectra and lifetime. The results indicate that the obtained Zn（OH）F:Eu3+ samples possess net-like and dandelion-like morphologies,which have an identical orthorhombic phase structure. It is found that the addition amount of raw materials such as NH4F and HMT plays a critical role for the formation of Zn（OH）F:Eu3+. If the addition amounts of NH4F or HMT are reduced by half, the hexagonal ZnO:Eu3+ sample with peanut-like morphology can be obtained. Under the excitation of UV light, both the as-prepared Zn（OH）F:Eu3+and ZnO:Eu3+ samples exhibit the characteristic emission of the doped Eu3+.
