PREPARATION OF PHOSPHORS BY PRECIPITATION FROM SOLUTION

PREPARATION OF PHOSPHORS BY PRECIPITATION FROM SOLUTION

Inorganic phosphors are prepared by separately introducing the anions and cations to form the phosphor into a reaction solution; maintaining in the reaction solution, throughout the reaction, an excess of up to 1 molar of the anion or cation; preventing local excesses of anions and cations; and, gro...

Zusammenfassung:Inorganic phosphors are prepared by separately introducing the anions and cations to form the phosphor into a reaction solution; maintaining in the reaction solution, throughout the reaction, an excess of up to 1 molar of the anion or cation; preventing local excesses of anions and cations; and, growing crystals of the phosphor to at least 0.5 micron.
