A series of Mn -doped zinc germinate ZGO:xMn (x = 0-0.05) nanorods was synthesized successfully using a hydrothermal method. XRD revealed that crystal phases of the ZGO:xMn were rhombohedral and in the R-3 space group. The Williamson-Hall equation was also used to explain the strain, nanocrystalline size, and stacking fault. Green LEDs were successfully fabricated by coating ZGO:Mn nanorods onto UV-LED chips. For high color purity, CIE of the fabricated green LEDs were (0.2404, 0.5428), which made this material a promising candidate for fabrication of UV-based green LEDs.
采用水热法成功合成了一系列锰掺杂的锗酸锌ZGO:xMn（x = 0 - 0.05）纳米棒。X射线衍射（XRD）表明，ZGO:xMn的晶相为菱面体，属于R-3空间群。还使用威廉姆森-霍尔方程来解释应变、纳米晶尺寸和堆垛层错。通过将ZGO:Mn纳米棒涂覆在紫外发光二极管（UV-LED）芯片上，成功制备了绿色发光二极管。为了获得高色纯度，所制备的绿色发光二极管的国际照明委员会（CIE）坐标为（0.2404, 0.5428），这使得该材料成为基于紫外光的绿色发光二极管制造的有前途的候选材料。
