Abstract

NaYbF₄:Tm³⁺ based-nanostructured materials have been synthesized by solvothermal method and sol-gel technique. Observed high intense UV-blue up-conversion luminescence, under low-power commercial 980 nm laser irradiation, have been applied to enhance photocatalytic activity. Thus, photocatalytic degradation of methylene blue, as an organic pollutant model, was proved as a unique photonic effect, converting incident NIR radiation before reaching the contaminated solution
