Abstract |
無機蛍光体は蛍光灯や白色LEDなどに使われている発光材料である。本研究では、外部からの物理的あるいは化学的な刺激を受けて発光特性が変化するフルオロクロミズムという新たな機能を無機蛍光体に付与することを目指した。実際に、水素ガスや過酸化水素など反応性の高い化学物質の存在下で発光強度が著しく低下するような応答性を確認することができ、化学センサなどへの応用を見込める無機蛍光体の合成に成功した。
Inorganic phosphors are luminescent materials that are widely used in fluorescent lamps and white LEDs. In this study, we aimed at creating a new function in inorganic phosphors; it is fluorochromism that can be recognized as changes of luminescent properties in response to physical or chemical stimuli. Actually we have succeeded in synthesizing inorganic phosphors that are highly responsive to reactive chemical substances such as hydrogen gas and hydrogen peroxide. We believe that they are promising as materials in developing new types of chemical sensors.
