Synthesis of carbon nitride crystals using flux method under ultra high pressure

我们尝试通过向含碳合金熔体中通入超高压氮气来合成氮化碳。我们可以确认在C-Na熔体体系中合成具有N/C > 1的高氮比的非晶碳氮化物。本研究中开发的合成方法适用于其他氮化物的合成。首次成功合成了单相的n-GaN纳米粒子。我们尝试将铕元素掺杂到氮化镓奈米粒子中，使其在紫外光的照射下产生红色的萤光。

We tried to synthesize carbon nitrides by supplying ultra high pressure nitrogen gas into alloy melt including carbon element. We could confirm the synthesis of amorphous carbon nitrides having high nitrogen ratio of N/C > 1 in a C-Na melt system. The synthesis method developed in this study was applied for the synthesis of other nitrides. As a result, single phase cubic-GaN nano-particles were successfully synthesized for the first time. We tried to dope europium element to the cubic-GaN nano-particles, leaded to the red fluorescent light in reaction to incidence of ultra-violet light.
