dc.description.abstractNowadays, the investigation of oxide based light emitting materials for white lightemitting diodes (w-LEDs) applications have generated interest due to the advantages such as long lifetime, low energy consumption, high luminescence efficiency and environmental friendliness [1]. These qualities make them a strong candidate for the solid state lighting, display devices, optoelectronic devices and light-emitting diodes (LEDs). In this work, we present results of Dy3+: BaWO4 and Dy3+: SrWO4 that present luminescence close to white color (Figure 1) left. They were synthetized using coprecipitation method. The emission spectra exhibit four emission transitions centered at around 486 nm, 576 nm, 665 nm and 760 nm corresponding to the transitions 4F9/26H15/2 (blue), 4F9/26H13/2 (yellow) 4F9/26H11/2 and 4F9/26H9/2 6F11/2 (red) respectively.Among these transitions 4F9/26H15/2 and 4F9/26H13/2 are observed to be strong whereas 4F9/26H11/2 transition is found to be relatively quite weak.The 4F9/26H13/2 transition is hypersensitive in nature and is strongly influenced by the environment around the Dy3+ ion site. It is observed in the luminescence spectra of these materials that the electric dipole transition is dominant compared to the magnetic dipole transition. The CIE diagram show emission close to white (Fig.1 right) for the five composition with little distortion of the color showing the influence of dopant concentration in the color of the emission.pt_BR
