摘要：
This paper reports the visible-light photocatalysts and luminescence quenching of ZrO2/AgCl:Eu3+ nanoparticles synthesized by the co-precipitation method as a function of AgCl concentration. XRD analysis indicated the presence of crystalline tetragonal ZrO2 and an AgCl phase. The synthesized ZrO2/AgCl:Eu3+ nanoparticles were observed to have a spherical morphology with diameters of approximate to 20nm. The photocatalyst with 2.5% mole fractions of AgCl showed effective degradation of methylene blue under visible light with the decolorization percentage reaching approximate to 95% in 180min. The red emission of Eu3+ in the ZrO2/AgCl:Eu3+ nanoparticles decreased with increasing AgCl mole fraction. Visible-light photocatalysts of ZrO2/AgCl:Eu3+ nanoparticles can be attributed to the presence of AgCl resulting in higher photoexcited charges separation, which can be confirmed by lower luminescence intensity.
