Abstract
The present invention relates to a production method of a phosphor comprising the steps of: forming a phosphor precursor in a liquid phase; drying the phosphor precursor; and firing the dried phosphor precursor to obtain the phosphor. At least one of the forming step, drying step and firing step is conducted in the presence of a binder.
Claims10
A production method of a phosphor comprising the steps of:
- forming a phosphor precursor in a liquid containing an inhibitor;
