  In this communication, we report the temperature dependence (3 to 300K) of
the electrical resistivity of BiS2 based layered PrO0.5F0.5BiS2 superconductor
at ambient and hydrostatic pressure of up to 3GPa. It is observed that Tc
increases with pressure at the rate of dTc/dP=0.45/GPa for PrO0.5F0.5BiS2
compound. It is envisaged that one may increase the Superconducting transition
temperature (Tc) of recently discovered PrO0.5F0.5BiS2 superconductor by
applying hydrostatic external or internal chemical pressure via suitable on
site substitutions.
