Abstract

Ultraviolet photo-excited luminescence from Cu-doped halosulphate phosphors has been investigated. The intense emission of the spectrum is assigned to electronic transitions 3d94s1 → 3d10 in Cu+ ions. Increase in photoluminescence (PL) peak intensity suggesting that Cu plays an important role in PL emission in the present matrix. However, limited hosts with Cu+ as luminescence center were studied due to difficulties in incorporating it in a luminescence form. Cu-doped halosulphate phosphors were synthesized by wet chemical method. X-ray diffraction and PL characterization of phosphors has been reported in this article. The article discusses the luminescence of Cu+ and the simple method of incorporation in various new hosts.
