| description | Over the past few decades, there has been a growing and insatiable demand for power consumption across the globe. In this multifaceted landscape of optoelectronic applications, the role of lighting, especially in the form of white-light LEDs stands as a vital component of our daily existence. These fourth-generation lighting devices have garnered significant attention from researchers due to their fundamental role in addressing the ever-increasing energy demands. This study investigates into the synthesis of phosphors Ba2V2O7:0.04Dy3+,0.03Eu3+ and Ba2V2O7:0.03Eu3+,0.04Dy3+ using the hydrothermal method, employing techniques such as X-ray diffraction and diffused reflectance spectra photoluminescence spectra for characterization. X-ray diffraction clearly affirms the successful integration/ incorporation of Dy3+ and Eu3+ ions within the Ba2+ lattice of the Ba2V2O7 host, without inducing any structural alterations. The diffused reflectance spectra reveal the emergence of a meta-stable state bridging the valence and conduction bands, a consequence of the Dy3+ and Eu3+ ion substitution in the Ba2V2O7 phosphor lattice. Photoluminescence spectra demonstrate that the synthesized phosphors emit a bluish-white color upon excitation. This study provides these groundbreaking lighting devices have demonstrated their spirit in a diverse array of applications. |
