METHOD FOR PURIFYING ELECTROLUMINESCENT MATERIAL, ELECTROLUMINESCENT MATERIAL AND ELECTROLUMINESCENT DEVICE

摘要

A purifying method which enables to efficiently remove Pd, and an electroluminescent material and an electroluminescent device obtained by utilizing such a method are disclosed. The method for purifying an electroluminescent material is characterized in that an electroluminescent material containing Pd as an impurity is treated with a material containing phosphorus for removing Pd.
