|Abstract:||Sulphide based phosphors activated with Bi and Mn ions were prepared by solid-state diffusion method. The emission and excitation spectra of SrS:Bi, SrS:Mn and SrS:Bi, Mn phosphors were recorded at room temperature due to their photoluminescence characterization as well as the energy transfer process. The photoluminescence study of phosphors shows the energy transfer from Bi<sup>3+</sup> to Mn<sup>2+</sup>. The thermo luminescence study of CaS:Mn and CaS:Bi was also carried out.|
