Abstract
กระบวนการสำหรับการสังเคราะห์ ฟอสฟอร์ซึ่งถูกเติม Mn4+ ที่มีความเสถียรของสี (color stable Mn4+ doped phosphor) รวมถึงการสัมผัสสารตั้งต้นของสูตร L, ในรูปแบบก๊าซ ที่ อุณหภูมิที่สูงขึ้น กับ ตัวออกซิไดซ์ที่ประกอบด้วยฟลูออรีน เพื่อก่อให้เกิดฟอสฟอร์ซึ่งถูกเติมด้วย M4+ ที่มีความเสถียรของสี Ax[MFy]Mn4+ I ที่ซึ่ง A คือ Li, Na, K, Rb, Cs, Nr4 หรือสารผสมของสิ่งเหล่านั้น; M คือ Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, Hf, Y, La, Nb, Ta, Bi, Gd, หรือสารผสมของสิ่ง เหล่านั้น; R คือ H, แอลคิลสายสั้น, หรือสารผสมของสิ่งเหล่านั้น; x คือค่าสัมบูรณ์ของประจุ [MFy] ไอออน; และ y คือ 5, 6 หรือ 7: Process for synthesis The phosphor which was added color stable Mn4 + doped phosphor (color stable Mn4 + doped phosphor) includes exposure to the substrate of the formula L, in gas form at elevated temperatures with an oxidizing agent containing fluorine To form a phosphor which was added with the color stabilized M4 + Ax [MFy] Mn4 + I where A is Li, Na, K, Rb, Cs, Nr4 or a mixture of them; M is Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, Hf, Y, La, Nb, Ta, Bi, Gd, or a mixture of them; R is H, short-chain alkyl, or a mixture of them; x is the absolute value of the charge [MFy] ion; And y is 5, 6 or 7:
