Abstract
Description
実験1では、Bi濃度を0.5〜10mol%の範囲となるように原材料紛体を混合し、各Bi濃度での発光強度を計測した。焼成温度は1600℃に設定した。また、励起光の光源には、ピーク波長(172nm)のXeエキシマランプを用いた。
実験2では、Bi濃度を1.0mol%と定め、燃焼温度を1000℃〜1700℃の範囲で変えて焼成し、そのときの発光強度を計測した。それ以外の実験条件については、実験1と同じである。
実験3では、特許文献1に記載された液相法(段落[0062]等参照)によって蛍光体YPO4:Biを合成するとともに、本実施例の合成手法に基づいて焼成温度1000℃、1600℃で合成し、発光強度を互いに比較した。ただし、本実施例(固相法)のBi濃度は1.0mol%としている。
