Abstract

The synthesis of the Li2SO4: Cu phosphor using a wet chemical method is reported here. The XRD technique showed the crystalline nature of the prepared material. The presence of Na and K in the host affected the observed photoluminescence characteristics of Li2SO4: Cu. Photoluminsecent emission spectra of Li2SO4: Cu phosphor showed a very strong prominet peak at 387 nm in the indigo region due to 3d9 4 s1 ↔ 3d10 transition of the Cu+ ion. The increase in peak intensity of the PL spectrum suggests that Cu+ acts as the luminescence center in the present matrix. Copyright © 2010 John Wiley & Sons, Ltd.
