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
