Abstract

Addition of methacrylic acid (MA) during preparation of ZnS doped with Mn2+ (ZnS:Mn) increased the photoluminescence (PL) due to 4T1-6A1 transition of Mn2+. According to X-ray fluorescence analysis and electron paramagnetic resonance spectroscopy, ion exchange between Zn2+ and Mn2+ through a preferential dissolution of Mn2+ was promoted by acidic additives. This caused that Mn2+ ions were isolatedly incorporated into ZnS. The X-ray photoelectron spectra show that the intensity of S 2p3/2 peak due to S6+ increased relative to that of S2- by virtue of carboxylic groups. The intensities of PL peaks at 450 and 580 nm, corresponding to polymethacrylic acid and Mn2+, respectively, increased after heating at 80°C for 1 week. We conclude that MA plays important roles on selective leaching to increase the amount of isolated Mn2+ ions, chemical interaction between ZnS:Mn and MA, and energy transfer to Mn2+, leading to the increase in PL intensity.
