Various Zn2-xSiO©þ:xMn based green phosphors were investigated in association with a co-dopant. The co-dopant incorporated into the phosphors are believed to alter the internal energy state of Zn2-xSiO©þ:xMn so that the improvement i º» ¿¬±¸¿¡¼ÀÇ ÁÖ¸ñÀûÀº ±âÁ¸ÀÇ Zn2-xSiO©þ:xMn °è ³ì»öÇü±¤Ã¼¿¡¼ MnÀÇ ¾çÀ» º¯È½ÃÄÑ ÃÖÀû Á¶°ÇÀ» ã°í ´Ù½Ã ¿©±â¿¡ Á¦ 2ÀÇ ¿ø¼Ò¸¦ ´Ù½Ã dopingÇÔÀ¸·Î½á ¹ß±¤ ÈÖµµ ¹× Àܱ¤½Ã°£À» ÃÖÀûÈÇÏ´Â µ¥¿¡ ÀÖ´Ù. µû¶ó¼ Zn2-x-ySiO©þ:(xMn, yMg)ÀÇ ³ì»öÇü±¤?
