Abstract

A new technique for the synthesis of luminescent powders of Ca1–x–yYbxEryF2+x+y solid solutions is proposed for the preparation of ceramics using ammonium fluoride and potassium fluoride as fluorinating agents. The phosphors show high upconversion luminescence energy yields (3-5.5%) indicating a low content of luminescence quenching impurities.
