Abstract
Single-phase powders of a KGd1.52Yb0.40Er0.08F7 solid solution with an average particle size of 350 nm are synthesized by co-precipitation from aqueous solutions with a different order of mixing reagents. Surface leaching processes of potassium are revealed and studied. The optimal temperature of thermal treatment (525 °C) is determined. It enables the achievement of the energy yield of erbium up-conversion luminescence of 1.30±0.02% at the excitation wavelength of 974 nm with a pump power density of 1 W/cm2.
