| Research Abstract |
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.
