Abstract:

This paper deals with optical absorption and photoluminescence properties of nanorange (22-65 nm) luminescent materials Co(1-x)Ce(x)WO(4) (where x = 0.01, 0.015, 0.02, 0.025 and 0.03) sintered in air at various temperatures. These compounds were prepared by the solution-based co-precipitation method and characterized by x-ray powder diffraction and thermal analysis. Optimum conditions for high luminescence emission were obtained.
