Abstract:
In this work nano range C0WO(4) powder samples doped with different concentrations of Ce3+ ions were prepared by coprecipitation method. The samples were also sintered at various temperatures and characterized using XRD,TG/DTA methods. It was found that the nano particle size increased with increase in sintering temp. The variation in optical absorption due to variation in sintering temperatures and variation in dopant Ce3+ concentration were directly reflected on the PL emissions. Upconversion PL is also reported for the Ce3+ doped samples.
