Description
(参考例1)
上記参考例1と上記実施例とから、参考例1で得られた蛍光体に導電性金属を含有せしめたものも、蛍光体のチャージアップが防止されるので、輝度が向上することが分かる。
(参考例2)
かくして得られた蛍光体に電子線を加速電圧3kVで照射した時の発光輝度(任意単位)に対する焼成時間依存性を評価し、その結果を図6に示す。図6から明らかなように、焼成時間1〜8時間でほぼ満足できる輝度を有する蛍光体が得られ、特に2〜4時間でより高い輝度を有する蛍光体が得られることが分かる。なお、焼成雰囲気としては、N2ガス中の場合により高い輝度を有する蛍光体が得られる傾向があった。
上記参考例2と上記実施例とから、参考例2で得られた蛍光体に導電性金属を含有せしめたものも、参考例の結果と同様な結果が得られ、焼成雰囲気としては、N2ガス中の場合に、より高い輝度を有する蛍光体が得られることが分かる。
