Hexagonal boron nitride was synthesized by pyrolysis using boric acid and melamine. At this time, to impart luminescence, rare earth cerium ions were added to synthesize hexagonal boron nitride nanophosphor particles exhibiting deep blue emission. To investigate the changes in crystallinity and luminescence according to the re-heating temperature, samples which had been subjected to pyrolysis at 900 °C were subjected to re-heating from 1100 °C to 1400 °C. Crystallinity and luminescence were enhanced according to changes in the reheating temperature. The synthesized cerium ion-doped hexagonal boron nitride nanoparticle phosphor was applied to the anti-counterfeiting field to prepare an ink that can only be identified under UV light.
采用硼酸和三聚氰胺通过热解合成了六方氮化硼。此时，为了赋予其发光性能，添加了稀土铈离子以合成呈现深蓝色发射的六方氮化硼纳米磷光体颗粒。为了研究根据再加热温度结晶度和发光的变化，将在900℃下进行过热解的样品在1100℃至1400℃下进行再加热。结晶度和发光随再加热温度的变化而增强。将合成的铈离子掺杂六方氮化硼纳米颗粒磷光体应用于防伪领域，制备了一种只能在紫外光下识别的墨水。
