The luminescent properties of HfO samples were studied considering calcinations carried out at different temperatures (1000, 1200, 1400 1600 °C). The results of XRD showed that the samples, synthesized by the precipitation method, have a crystalline phase in the monoclinic system, and the size of the crystallite increases from 22.8 nm, for sample calcined at 1000 °C, to 41.6 nm for the one calcined at 1600 °C.

热处理对沉淀法合成HfO2发光性能的影响


考虑在不同温度（1000、1200、1400 1600 °C）下进行的煅烧，研究了 HfO 样品的发光特性。 XRD结果表明，沉淀法合成的样品具有单斜晶系晶相，晶粒尺寸从1000 ℃煅烧样品的22.8 nm增大到1000 ℃煅烧样品的41.6 nm。在 1600°C 时。
