Optical absorption and photoluminescent studies of cerium-doped cobalt tungstate nanomaterials

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.
