采用水热法制备了不同Mn2+掺杂量的单相ZnAl2O4荧光粉。用X射线衍射仪、透射电子显微镜、光致发光光谱和振动样品磁强计对荧光粉进行了表征。X射线衍射仪和透射电子显微镜的测试结果表明，所合成的纳米粒子为八面体和六方体形的单晶，并且经过热处理后，这种形状发生了变化。在427 nm激发下观察到掺杂铝酸锌的绿光发射。随温度变化的荧光光谱显示两个发射峰，随着温度的降低呈现出不同的位移趋势。铝酸锌纳米颗粒的室温磁滞回线表现出磁性行为，并且随着Mn2+掺杂量的增加，磁性逐渐消失。
The single-phase ZnAl2O4phosphors with various components of Mn2+dopant were fabricated by using hydrothermal method. The phosphors has been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence (PL) spectra and vibrating sample magnetometer (VSM). The results of XRD and TEM measurements showed that the resultant nanoparticles were single crystal with octahedral and hexagonal shape, and after annealed, this shape had change. Green emission was observed from doped zinc aluminate with 427nm excitation. The temperature-dependant PL spectra revealed two emission peaks which exhibited different shifting tendency with a decrease in temperature. The room-temperature hysteresis loops of zinc aluminate nanoparticles showed magnetic behavior, and the magnetism disappeared gradually with the increase of Mn2+doping contents.
