Phosphor |
| abstract |
An object of the present invention is to provide a red light-emitting phosphor having high luminous efficiency and a method for producing the same.nn n n The solution of the present invention is to provide a red luminescent phosphor mainly composed of lanthanum potassium fluoride, and the basic composition of the surface is a phosphor represented by the following formula (A) KaSiFb (A); characterized by: manganese The ratio of the amount of manganese present on the surface of the phosphor to the total amount of total elements present on the surface of the phosphor is less than 0.2 mol%. This phosphor can be produced by washing a product obtained by reacting a reaction solution containing potassium permanganate with a cerium source by washing with a weak acid. |
