we report the preparation and optical properties of copper doped zinc sulphide aqueous colloid.The effects of size and quantum confinement on the green luminescence properties of ZnS:Cu have been studied.UV absorption shows the energy gap of ZnS:Cu nanocrystallites is 4.186eV.The emission measurements show a large blue shift of the G-Cu luminescence.Luminescence decay times measured in the case of nanoparticles are much faster than that of bulk ZnS:Cu.
