Abstract
Description
出発原料として、SrCO3、BaCO3、CaCO3、Eu2O3、MgO、ZnO、SiO2を用い、これらを所定の組成になるよう秤量し、ボールミルを用いて純水中で湿式混合した。
上記蛍光体の製造例における試料番号1〜8、試料番号12および15と同様の青色蛍光体を使用し、上述した交流面放電型PDPの例と同様にして図2の構成を有するPDP(42インチ)を作成し、輝度維持率の評価を行った。加速駆動(実駆動3000時間相当)した後の輝度維持率(輝度Yの初期値に対する駆動後の値の割合)を表2に示す。パネルは青色1色固定表示とした。なお、表2において*印を付した試料が比較例、*印を付さなかった試料が実施例である。
