Description
先ず、酸化物ガラス粉末を調製した。表1及び表2に示す組成となるように各ガラス成分を秤量して混合し、この混合物を白金ルツボ中において、表に示す溶融温度で1時間溶融してガラス化し、フィルム状に成型した。フィルム状のガラスをボールミルで粉砕した後、325メッシュの篩に通して分級し、酸化物ガラス粉末を得た。得られた酸化物ガラス粉末について、軟化点温度を示差熱分析装置により求め、結果を表1及び表2に示した。
上記実施例と同様に、表3及び表4に示す組成となるように各ガラス成分を混合して、酸化物ガラス粉末を調製し、得られた酸化物ガラス粉末と、表に示す蛍光体粉末を、表に示す配合比で混合して、上記実施例と同様に予備成型体を作製し、これを焼成して発光色変換部材を得た。
