ZnO nanocrystals doped with Cd, Mg, Mn, and Fe ions were obtained by thermolysis of a family of metal cupferrates. The nanocrystals were characterized by X-ray diffraction, energy-dispersive X-ray analysis, transmission electron microscopy, UV-visible, luminescence, and excitation spectroscopy. The band gap of the nanocrystals can be tuned in the range of 2.9-3.8 eV by the use of the dopants. In most cases, the nanocrystals are sufficiently defect-free to exhibit band edge luminescence.
通过一系列金属铜铁试剂的热解制备了掺杂镉、镁、锰和铁离子的氧化锌纳米晶体。通过X射线衍射、能量色散X射线分析、透射电子显微镜、紫外可见光谱、发光光谱和激发光谱对纳米晶体进行了表征。通过使用掺杂剂，纳米晶体的带隙可在2.9 - 3.8 eV范围内调节。在大多数情况下，纳米晶体具有足够少的缺陷，能够表现出带边发光。
