METHOD FOR TREATING MN-ACTIVATED COMPLEX FLUORIDE PHOSPHOR |
| 摘要 |
A method for treating a Mn-activated complex fluoride phosphor is provided wherein a preliminarily-prepared red phosphor of a Mn-activated complex fluoride represented by the following formula (1):;A2MF6:Mn (1);wherein M represents at least one tetravalent element selected from Si, Ti, Zr, Hf, Ge and Sn, A represents at least one alkali metal selected from Li, Na, K, Rb and Cs provided that at least Na and/or K is contained, is heated in a substantially oxygen atom-free gas but containing a fluorine atom at a temperature of at least 50° C. |

1. A method for treating a Mn-activated complex fluoride phosphor comprising:
heating a preliminarily-prepared red phosphor of a Mn-activated complex fluoride represented by the following formula (1):
A2MF6: Mn (1) wherein M represents at least one tetravalent element selected from the group consisting of Si, Ti, Zr, Hf, Ge and Sn, A represents at least one alkali metal selected from the group consisting of Li, Na, K, Rb and Cs provided that at least Na and/or K is contained, in a substantially oxygen atom-free gas containing a fluorine atom at a temperature of at least 50° C. |
