In the present work, we have investigated photoconductivity properties in Pr-doped ZnS powders. ZnS: Pr powder has been prepared by simple heat treatment technique at temperature of 800 0 C. I-V characteristics i.e. voltage dependence of photocurrent under UV illumination (λ=365 nm) exhibits non-Ohmic (r < 1) behavior at low as well as high voltage regimes. The crystallite size of ZnS:Pr corresponding to main XRD peak is estimated as 37.25 µm. The micro strain is calculated as 0.46.

Summary: ZnS:Dy and (ZnS:Mn,Dy) phosphors have been prepared in an inert atmosphere of pure nitrogen gas at about (950 AE 20)C. The photo luminescent (PL) and electroluminescent (EL) and spectra of these phosphors have been studied at room temperature. The purpose of this work is to know in what ways the spectraal characteristics of ZnS phosphors are affected by the introduction of Dy 3þ and Mn 2þ ions and also to determine unambiguously the electronic transitions involved in the energy transfer.
